Why we recommend it
A darkly seductive spin-off into a fractured paranormal world where power and prophecy collide. Perfect for fans who crave morally grey leads, smoldering enemies-to-lovers heat, and a heroine who refuses to be tamed. The atmosphere is gothic and dangerous, the tension drawn taut, and the romance hard-won. If you love your fantasy bloodthirsty and your chemistry combustible, this volume delivers obsession with teeth.
