About The Book

How to Train Your Dragon meets Skandar and the Unicorn Thief as a brother and sister go to a summer camp aimed at future dragon riders in this first book in the high-flying middle grade adventure series Dragon Force.

Twelve-year-old Lance Lo dreams becoming part of the Dragon Force, a team of heart-bonded humans and dragons dedicated to protecting the world from dangerous magical creatures. So he can’t wait to attend Camp Claw with his younger sister, Zoe, and begin learning about dragon training.

But Lance quickly finds himself falling behind in the lessons and activities. He’s the only camper who’s failed to achieve a heart-bond with a dragon, and with Zoe impressing everyone with her natural ability, Lance struggles with jealousy.

But when Camp Claw is mysteriously attacked in the dead of night, Lance has to level up—in spirit and in skill—because it’s up to him and the latest recruits to get to the root of the growing danger and prove they’ve got what it takes to save the day.
