Harvested for My Adopted Sister's Heart

After a werewolf bonding ceremony, a woman searching for herbs in the Black Forest is ambushed by rogue wolves and left with injuries that rob her of any chance to have pups. Her mate and parents seem devoted during her recovery, but she overhears them calmly planning to take her heart for her adopted sister. Recording the conversation on her phone, she vows to return with a new allegiance and a far colder resolve.
