In this riveting novel from international bestselling author Daniel Kalla, a Vancouver doctor and a detective face the deadly consequences of the opioid crisis as they track down the supplier of fentanyl that landed a group of teens in the ER with critical overdoses.

“Michael Crichton ought to be looking over his shoulder.” The Chronicle Herald

Deliberately or not, they must’ve been poisoned…And if it happened to them…

There will be others.

Dr. Julie Rees, a toxicologist and ER doctor, is stunned when her emergency room is flooded with teenagers from the same party, all on the verge of death. Julie knows the world of opioids inside and out, and she recognizes that there’s nothing typical about these cases. She suspects the teens took—or were given—fentanyl. But why did they succumb so quickly?

Detective Anson Chen is determined to find out. He and Julie race to track down the supplier of the deadly drugs. But the trail of suspects leads everywhere, from unscrupulous street dealers to ruthless gang leaders who hide behind legitimate business fronts and the walls of their mansions.

As Anson and Julie follow clues through the drug underworld, Julie finds herself haunted by memories of her troubled past—and the lover she lost to addiction. When other overdoses fill the ER—and the morgue—Julie realizes that something even more sinister than the ongoing fentanyl crisis is devastating the streets. And the body count is rapidly rising.

A gripping thriller, The Last High explores the perfect storm of greed, addiction, and crime behind the malignant spread of fentanyl, a deadly drug that is killing people faster than any known epidemic.


The house music courses through Alexa. The hypnotic beat and melting layers of sound feel as if they come from within, as if her heart is the amplifier. And the warmth is so enveloping. Like being lowered into the most perfect bubble bath. The bliss is almost unbearable.

Alexa can’t lift her head off her chest, but she can move her eyes. With a quick sweep of the room, she sees all the friends who matter most to her—Rachel, Nick, Joshua, Grayson, and Taylor. The only ones who matter at all, really.

Taylor, her very best friend, is slouched at a weird angle on the couch beside her. Taylor had promised to ensure Alexa got some alone time with Josh at the party, even though she has a crush on him, too. Typical Taylor, always putting friends first. Her eyes are still open, but the pupils are tiny as pinholes. And her complexion! It’s grayish blue, while her lips have turned almost purple. So strange, but so beautiful.

Alexa shifts her gaze to the left and sees Josh and Gray sprawled out on the other couch, propped up only by their abutting shoulders. Josh’s eyes are as glassy as Taylor’s, while Gray’s are shut altogether. They’re both so still. And Josh’s exposed arms are mottled deep dark blue. Alexa wishes she could tell him just how much she loves him. Tonight was supposed to be the night.

Alexa looks down at her own hands. Her fingers feel foreign to her, and the color of her nails matches that of Taylor’s lips. She knows it’s not right, but it’s still so wild.

The floating warmth intensifies. Alexa feels as though she’s falling off the couch, even though she’s not moving. She’s never drunk anything more than a beer or two in her sixteen years. How could one cup of Nick’s punch make her so woozy?

Somewhere in the back of her brain she can hear her mother’s panicked voice—a distant scream—telling her to breathe. But her mom’s nowhere near the party.

Alexa finds it all kind of funny. She wants to laugh. She wants to tell Taylor how exquisitely wrong it all is. But she can’t even move her lips. Besides, dreams are stealing over her now. And she can’t hold on any longer.

Praise for The Last High

“A thrilling, front-line drama about the opioid crisis.”

“Kalla has long had his stethoscope on the heartbeat of his times. . . . In his latest, the focus is on Vancouver’s opioid crisis. . . . [A] lively story.”
— Toronto Star

“A riveting thriller, The Last High features the most evil and insidious of villains: opioids. This important, must-read book is not only well-researched and entirely realistic, it gives a human face to a devastating epidemic.”
— ROBYN HARDING, internationally bestselling author of The Arrangement and The Party

“Kalla is terrific at building suspense as the case progresses, uncovering a web of dealers, sellers, and users.”
— The Globe and Mail

“A sobering glimpse into the drug overdose crisis. . . . An entertaining, if slightly eerie read.”
— Vancouver Sun

Praise for We All Fall Down

“A tightly plotted thriller, energetic and completely believable. Kalla knows how to build a suspenseful story that doesn’t stretch the bounds of plausibility. He also knows how to build realistic characters and put natural-sounding dialogue into their mouths, something many better-known medical-thriller authors often struggle to do. . . . [a] top-drawer thriller.”

“A fast paced thriller with an historical overlay and a dash of romantic tension.”
 Vancouver Sun

“A superbly written suspense novel, completely believable in its frightening premise and masterful in execution. Kalla inherits the mantle of Michael Crichton, devising a plot in which an ancient pestilence meets a scourge of human egotism and misplaced faith, resulting in the potential for a worldwide cataclysm. Much more than a medical thriller, We All Fall Down is both a vivid history lesson and a heart-pounding warning, resulting in a page-turning obsession.”
— STEVEN HARTOV, New York Times bestselling author of The Soul of a Thief

“A great thriller hero never hesitates—despite, or perhaps because of, her checkered past and uncertain future. By that standard, Dr. Alana Vaughn is the woman readers will want on their side when stalked by the most terrible of all plagues in We All Fall Down.”
— JUSTIN SCOTT, author of The Shipkiller, Rampage, and the Isaac Bell adventure novels with Clive Cussler

Praise for Of Flesh and Blood

“This novel should appeal to any reader who enjoys a rich medical narrative that combines the past with the present and throws into the mix visionary doctors, supportive nurses, hospital politics, children with cancer, celebrity patients, a lethal infection, adultery, and unrequited love.”
— Library Journal

“Daniel Kalla plunges us straight into the frenzied pace of the OR and a medical drama that spans a hundred years. He’s a strong storyteller who keeps his characters moving and struggling, and we’re right there, struggling with them, rooting for them.”
 Vancouver Sun

“Daniel Kalla deftly portrays the triumph and heartbreak of life-or-death matters.”
— SUSAN WIGGS, New York Times bestselling author

“Daniel Kalla, a worthy successor of Robin Cook, shows as deft a hand in penning this compelling tale as he no doubt does in the operating room.”
— EILEEN GOUDGE, New York Times bestselling author

Of Flesh And Blood is great story-telling. Daniel Kalla has written a remarkably compelling novel of vivid, driven characters and the hard choices they are forced to make.”
— DAVID LISS, bestselling author

Praise for Cold Plague

“A terrific read.”
— The Globe and Mail

 “A well-written novel . . . Kalla, an emergency-room physician, employs just enough medical realism to carry a wild tale through one cliff-hanger chapter after another.”
 Library Journal

“Similar in many ways to Michael Crichton and even Dan Brown’s bestsellers, Cold Plague is testament to just how good commercial fiction can be: entertaining, informative, and downright fun.”
— Winnipeg Free Press

“Plenty of suspense and layering the kind of scientific detail the fans of the medical thrillers crave. Recommended to fans of Robin Cook and other such A-listers.”
— Booklist

Praise for Blood Lies

“Kalla’s well paced medical thriller has twists that surprise us, but always make sense.”
Entertainment Weekly

“Kalla strikes again with another perfect page-turner.”
— LEE CHILD, New York Times bestselling author

“Fast-paced and smartly written . . . Kalla has quickly matured into a force to be reckoned with. . . . Blood Lies springs several fresh surprises on the reader (including one whopping great shocker).”
— Booklist

“Fans of Presumed Innocent will find welcome echoes of that modern classic in Blood Lies. The twists are well done, and Kalla has a gift rare in the thriller field for creating sympathetic characters.”
Publishers Weeklystarred review

“Kalla continues his rapid rise in the thriller ranks with a gripping fourth novel.”
— Seattle PI

Praise for Rage Therapy

“Kalla navigates the emerging fields of impulse and rage control therapy, and the issue of doctor/patient abuse, turning it all into an ingenious thriller.”
 Ottawa Citizen 

— Vancouver Sun

“His first novel, Pandemic, was as fine a medical thriller as I've ever read; his newest, Rage Therapy, is a taut psychological thriller that will pull you into a world of sexual deviancy, murder, and mind games. A very good read.”
— NELSON DEMILLE, New York Times #1 bestselling author

Rage Therapy is a compelling story. It’s layered and nuanced. Kalla might well grow to be the James Patterson or John Grisham of the medical world.” 
January Magazine

Praise for Resistance

“Kalla builds suspense and keeps the medical action moving.”
— The Globe and Mail

“Daniel Kalla’s prescription for a perfect thriller includes snappy characters, a pace that sweeps up a reader and not too much technical jargon . . . the kind of magnetic story you can't put down. And the twist at the end of the book is the flourish that caps a strong story.”
Vancouver Province

“[Kalla] is back with another gripper.”
— Ottawa Citizen

“[Kalla] continues his remarkable side career as the author of knowledgeable, but very scary medical thrillers.”
 Seattle PI

Praise for Pandemic

“Very much in the Michael Crichton school of cutting-edge scientifically rooted thrillers. Pandemic is an absorbing, compulsive thriller, the sort of book you could stay up too late reading. I’d advise against that, however. With all the bugs going around, you’re going to need your immune system functioning at full strength.”
— Vancouver Sun

“Kalla’s ripped-from-the-headlines plot and confident command of both language and medicine make this sobering book a pleasure.”
— Publishers Weekly

Pandemic starts fast and never lets up on the suspense . . . Kalla juggles the many narrative balls easily, manages to insert a little romance, puts his protagonists in plenty of danger and drives his complex plot to a rousing climax.”
— Edmonton Journal

“Michael Crichton ought to be looking over his shoulder. He has some serious competition in Kalla.”
The Chronicle Herald

Pandemic is an absorbing, compulsive thriller, the sort of book you could stay up too late reading.”
— Vancouver Sun

“Daniel Kalla expertly weaves real science and medicine into a fast-paced, nightmarish thriller—a thriller all the more frightening because it could really happen.”
— TESS GERRITSEN, author of Body Double

“Kalla is a rocket ship of a writer. He moves to the front of the pack with a thriller that will grab you from page one and never let you go.”
— KEITH ABLOW, author of Psychopath

Pandemic is fast, fierce, and frightening. Kalla delivers a shot of adrenaline in a medical thriller that really thrills.”
— DON WINSLOW, author of California Fire and The Life and Death of Bobby Z

Pandemic is a totally compelling novel, one of those rare thrillers that lays out a scenario that is not only possible, but terrifyingly probable.”
— DOUGLAS PRESTON, author of Relic and The Codex

“At last! A new thriller writer worthy to join the Ludlum, DeMille, le Carré club. Not just a great read, a real treat.”
— BEVERLY SWERLING, author of City of Dreams: A Novel of Nieuw Amsterdam and Early Manhattan

Pandemic is a sizzler. A killer epidemic that may go global—convincing and terrifying.”
— BARBARA D'AMATO, author of Death of A Thousand Cuts and White Male Infant
