Now with a brand-new look and bonus content!

A by-the-book teen must learn to embrace the beauty in chaos in this New York Times bestselling novel by Morgan Matson about friendship, finding yourself, and all the joys in life that happen while you’re busy making other plans.

Andie has a plan. And she always sticks to her plan.

Future? A top-tier medical school.
Dad? Avoid him as much as possible (which isn’t that hard considering he’s a congressman and never around).
Friends? Palmer, Bri, and Toby—pretty much the most awesome people on the planet, who needs anyone else?
Relationships? No one’s worth more than three weeks.

But her perfectly predictable summer goes into a tailspin when a political scandal costs Andie her pre-med summer internship and lands both her and Dad back in the same house for the first time in years.

Suddenly she’s doing things that aren’t Andie at all—working as a dog walker, doing an epic scavenger hunt with her dad, and maybe, just maybe, letting the super-cute Clark get closer than she expected. Palmer, Bri, and Toby tell her to go with the flow, but can she really let go of her control?

Raves and Reviews

"Fans will enjoy sinking into this immersive summer read."

– Publisher's Weekly, February 8, 2016

"A touchingly sweet story about friendship, loss, family, and love. How nice it is to also find a book that steers clear of clichéd girl drama in favor of portraying long-standing and supportive friendships. Romance fans will find plenty to enjoy, as Andie gradually lets down her guard and risks the messy and unpredictable wonder of first love. A novel best read on a lazy summer day with sand between the toes."

– Kirkus Reviews, March 1, 2016

"The most interesting things tend to happen when plans are upended, and Andie’s story is no exception....a genuine pleasure"

– VOYA - Starred Review, April 2016

"Matson...skillfully combines elements of romance, family relationships, friendship, and careers. Over the course of a summer, Andie and her friends are forced to come to terms with trust—never a simple matter—and Matson gives the subject the sensitive treatment it deserves."

– Booklist, March 30, 2016

"Morgan Matson = best friendships + best families + best romances! Her characters come alive through tiny details that make you feel like you've always been best friends. And if you've recently had a disappointment, this book will help you find the hope hiding there. P.S. Clark is bae. Seriously. Hands off."
