In retaliation, Finn freezes life-support financing for Zoe's comatose brother Jack, leaving her cornered and desperate.
Finn's estranged half-blood brother Asher steps into the crossfire, having harbored secret devotion toward Zoe for nearly a decade. Defying clan hierarchies and bloodthirsty werewolf mercenaries, Asher bankrolls Jack's medical care and fights alongside Zoe. Together, the battle-hardened hunter and outcast prince risk civil war to dismantle Finn's tyrannical reign.
