Bestselling author Tony Abbott returns with the next full-length book in the Copernicus Legacy series, a globe-trotting adventure packed with more riddles, puzzles, and secret histories. The hunt for Copernicus's first relic sent Wade, Darrell, Lily, and Becca to the far reaches of the world and put them in serious danger. But they never imagined Sara Kaplan—Darrell and Wade's mother—would be kidnapped by the conniving Galina Krause. Now they must race the evil Teutonic Order to find the Serpens relic and rescue Sara before it's too late.

Fans of Rick Riordan and Ridley Pearson will love this epic series, which is filled with suspense and action.
