The Copernicus Legacy

A secret past can destroy the future. It all begins when Wade Kaplan receives a strange, coded email from his uncle Henry, shortly before the old man's sudden and suspicious death. He sets off for Germany to attend the funeral with his father, Roald, and his three friends Darrell, Lily, and Becca, only to 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, which sends them to a dark and creepy family tomb.

The hunt for the first relic in Copernicus' legacy has sent Wade, Darrell, Lily, and Becca to the far reaches of the world and put them in serious danger. But they never imagined joining this quest would come at such a high cost. Sara Kaplan - Darrell and Wade's mother - has been kidnapped by the conniving Galina Krause. Which means the stakes couldn't be higher for the Kaplan family as they race across cold, desolate landscapes, speedboat through narrow canals, and sprint through busy city streets in search of the sought-after relic called the Serpens.

It's been two months since the Kaplan family hunted down the Serpens relic. But when the evil Galina Krause suddenly and violently reappears, Wade, Darrell, Lily, and Becca have no choice but to face her again.
