Thirteen-year-old Blake Wyatt dug his bloodied fingers into the splintered railing of the ancient ship, struggling for footing in the violent storm. Minutes ago he was texting his friends in his boring history class. Now, Blake finds himself aboard the sinking Santa Maria-with the great Christopher Columbus begging for his help. The Admiral is about to be murdered-Dagonblud's latest victim in his quest to erase the world's history so he can replace it with his evil empire. Blake is the last surviving Sapphire Traveler who can save him. He must master his incredible new powers so he can sneak through time and destroy the Tolucan leader. But Dagonblud is planning a big surprise. Will Blake succeed where all others have failed? The only thing that is certain is that Blake's life, and the world around him, will never be the same.
