The hunt for the first relic in Copernicus's 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. Along the way, they meet another network of Guardians that may help them complete their journey, but will the kids get to Sara in time to save her life?

Filled with more riddles, puzzles, and secret histories, The Serpent's Curse is the second suspenseful book in bestselling author Tony Abbott's exciting Copernicus Legacy series.
