RICK RIORDAN meets DAN BROWN in this epic historical adventure series packed full of puzzles, clues and edge-of-your-seat excitement!

Legend has it that Copernicus found twelve powerful relics that could harness the cosmos and transport people through time when assembled in the shape of an astrolabe. Recognising the astrolabe’s terrible power, Copernicus hid the relics in far-flung corners of the globe and assigned loyal Guardians to pass down the duty of protecting the relics across the ages.

In the wrong hands, the astrolabe could control the world. That’s exactly what Galina Krauss and her powerful Teutonic Order plan to do once she collects all the pieces and reassembles them. She’s already infiltrated the Guardians and broken down their defences. Humankind won’t know what’s happened until it’s too late.

What Galina doesn’t know is that a letter, the Guardians’ last cry for help, has fallen into the hands of four young friends – Wade, Lily, Darrel and Becca. Four young friends who are about to find themselves caught up in a centuries-old battle to save fate itself…

The Copernicus Legacy

Filled with pulse-pounding action and cryptic codes, The Golden Vendetta is the third engrossing book in bestselling author Tony Abbott's cloak-and-dagger series for young readers. Fans of Rick Riordan and Ridley Pearson will love this adventurous series.

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. Now they must race to find an artifact said to be crafted by Leonardo da Vinci himself-perhaps the strangest Guardian of all. Along the way, they uncover another layer to Galina's sinister endgame . . . and there might not be enough time to stop it.
