There’s no turning back for Neva Grant. To find a killer, she must seduce the boldest male in the Sinclair pack. Her twin sister lies in a hospital bed, fighting for her life, the fourth and only surviving victim of a vicious attacker. The werewolf rangers suspect the Sinclair pack, and the only way Neva can infiltrate their close-knit ranks is to unleash the wildness within and offer herself to Duncan Sinclair.
