Despite a lifetime of bad luck, Teylin Walker remains determined to forge a new path for herself after leaving her abusive mother behind to chase her dream of becoming an actress in Los Angeles. But after a chance encounter with a boy possessing the extraordinary ability to turn invisible, she is thrown into a world beyond her wildest imaginings. Now danger follows her every step as the criminal syndicate known as the Coterie will stop at nothing to capture the boy and keep their secrets under lock and key–even if it means silencing Tey forever.

Tey miraculously survives, but at a cost. Enslaved and transported to a mystical chain of islands halfway across the Pacific, she discovers more children with dangerous and mysterious powers who are either killed for their abilities or used as pawns by the Coterie. Dubbed Shadowborn, they possess no memory of their origins, a lethal secret that Tey is determined to uncover.

Desperate to break free, Tey aligns herself with the dashing bounty hunter, Rob Stryker, who offers a glimmer of hope for escape. But as she grapples with her growing feelings for Rob and her burning desire to help the Shadowborn, the islands' hold on her grows stronger. When she rescues an injured Shadowborn from the clutches of a cruel master, Tey must make a fateful choice between her own freedom and the lives of those she has come to love.
