“Book Descriptions: With their sixteenth birthday fast approaching, orphaned twins Lia and Tyler Ford are still settling into their new normal in Sydney, Australia. Life with their paternal grandmother—their sole remaining, living family member—is a million miles removed from their former life with their parents in Ardsley, New York. Their grandmother is wonderful, their new school friends are nice, and Sydney is a perfectly fine place to live, but life these days for the Ford twins is not what anyone expected it to be.
Lia wouldn't have thought life could surprise her any more than it already has, but the arrival of a strange young man with an even stranger message turns what's left of her fractured world upside down in an instant. She and Tyler suddenly have more questions than ever before about their family's mysterious past, but also—finally—the chance to maybe fill in some of the many gaps in their knowledge of their family's history. That possibility has them readily following their unexpected visitor, Coen, to Gaea: a parallel universe which perfectly mirrored Earth millennia ago, though the two worlds have evolved to be markedly different realms today.
Gaea is in crisis. The North has already fallen, and the people of the South live in fear of a force so evil and powerful it may be impossible to defeat. With an empire hanging in the balance, the stakes are impossibly high, as are the expectations being placed on Lia. She must rise to the challenge and play her part in the resistance, or die trying—as the people of Gaea surely will if she fails. And, if Lia and Tyler can stay alive long enough on their treacherous journey, they might find out not only who they really are, but who they're destined to be.” DRIVE
