Werewolf. Baker. Spy. Empathy-squashing drugs have sent shifter society into a tailspin. Only one person is innocuous enough to infiltrate the culprit's pack —- Ember Wilder-Young, packless wolf and expert baker. Unfortunately, cupcakes alone aren't sufficient to soften her new employer's hard heart. Instead, Ember is faced with an impossible dilemma. Will she risk the lives of shifters everywhere by rejecting her boss' offer of pharmaceutical initiation into the pack? Or will she imbibe the very drugs she's been sent to wipe out and lose her own humanity in the process? The grand finale of the Wolf Legacy Quartet concludes the tale that's been described as "intense and full of emotions."
