Sadie has finally earned her place at Gilded Academy, training alongside the elite angels who protect Skyborne. She's learning their combat techniques, their protocols, and their unwavering loyalty, all in preparation for the inevitable confrontation with the realm's most dangerous threat: her half-sister, Myra.

The problem? Sadie's never actually met her.

Filled with questions no one wants her to ask, Sadie tries to keep her head down and follow orders. But when Luca—a mysterious shadow-wielder with gray wings and an even darker past—pushes her to seek answers, everything changes. He's everything the Gilded warned her against, yet something about him pulls Sadie closer than she knows is safe.

A mission to the treacherous Outlands spirals into chaos, forcing Sadie to confront truths about her family, her powers, and herself that shatter everything she believed. Caught between Luca's dangerous allure and Soren's steadfast protection, between duty to her team and loyalty to her blood, Sadie must navigate a web of lies that threatens to destroy everyone she cares about.

When hidden agendas surface and alliances crumble, Sadie learns that heroes and monsters are separated by a single choice—and she's running out of time to make it.
