When Ada's father is framed for a crime he didn't commit, she and her four best friends set out to find the truth. But as their investigation deepens, Ada begins to unravel shocking secrets about those closest to her. The tension rises when her feelings for Luke, one of her besties, become undeniable. Though they fight against their attraction, they eventually give in, adding further complications to an already dangerous situation.
The real turning point comes when betrayal strikes close to home. Nathan, a close friend she once had a crush on, reveals his feelings for her-feelings so strong that they prevent him from going through with a deadly mission. In the final confrontation, Ada is faced with a choice to kill him, but not before witnessing the tragic death of her cousin. The loss shakes her to the core and forces Ada to confront the truth about her family: they've secretly ruled the underworld for generations.
This revelation sends Ada into a downward spiral, and with her family's fate hanging in the balance, she's pushed to embrace her darker side. Her softness could cost them all, and she learns that only by hardening her heart can she protect the ones she loves. The journey forces Ada to become someone unrecognizable-cold, determined, and powerful. What she doesn't know is that this dark transformation will forever change her, and those around her, in ways she could never have predicted.
