The Forbidden Stone (The Copernicus Legacy, #1)

Rick Riordan meets Dan Brown in this exhilarating and adventurous new tween series from beloved and bestselling author Tony Abbott.

The Copernicus Legacy has everything middle-grade readers love-an international adventure, a compelling friendship story, and a mission that draws on history and astronomy. Readers who loved Percy Jackson will be eager to follow our heroes on this six-book, six-novella journey and excited to enter a sweepstakes to participate in a real-life scavenger hunt hosted by Tony Abbott that lets the reader become part of the story.

It all began when four friends-Wade, Lily, Darrel, and Becca-received a strange, coded email from Wade's uncle Henry shortly before the old man's sudden death. They set off for Germany to attend the funeral with Wade's father, Roald, and discover that Uncle Henry left them yet another baffling message that they suspect is the key to figuring out how and why he died.

The message leads to a clue, and the more clues they discover, the farther they travel down a treacherous path toward an ancient, guarded secret. Soon they are in a breathless race across the globe, running for their lives as a dangerous shadow organization chases them around every corner. Their only hope of saving themselves-and the world that they know-is to find twelve magical relics from a hidden past that will unlock the Copernicus Legacy.
