Tiger Betrayed — Tressie Lockwood

Someone is killing shifters, and Siberia is more like Hell than Heaven. What's worse, Deja learns her twin daughters have a gene that could cause them to mutate during their first shift, and it's passed down from her. If nothing else, Deja figures she has her husband to lean on, and they can get through this trial together. There's only one problem--Heath walks away from her when she needs him most. Betrayal springs up from several directions--friend, foe, and even family--throwing Siberia and its residents' lives into total disarray. Someone will die, but what Deja chooses to do and who she trusts could destroy them all when the Spiderweb organization raises its ugly head for the last time.
