Carrying the Alpha's Secret Heir

I thought our Alpha, who was my secret boyfriend, had prepared a celebration for me after I attended a werewolf conference in his stead. It turns out, the celebration wasn't for me. It was for his Beta and her unborn child, which she claimed was his. Unbeknownst to them, I was also pregnant. The Beta plotted to kill my unborn baby when I revealed this. Feeling unwanted and discarded, I was nonetheless given a chance at a new life—one I intend to use for revenge.
