Being a wolfless hybrid was bad? Yes, but not as bad as being rejected by your groom three days before your wedding, in favor of your younger sister!~~~Sue was an outcast from birth, and she grew up stomaching ridicules and insults despite being a princess in starlight pack. Instead of wallowing in self pity, Sue strives for strength and soon becomes a strong fighter.Having been rejected multiple times for being the pack’s freak, Sue was over the moon when she unexpectedly gets accepted by her present mate whom she’s presently engaged to. However, when she’s rejected again, and is replaced by her sister this time, she believes all hope is lost for her, not knowing fate has something else in store for her.In a mission that’s supposed to kill her, she ends up coming across her mate in the monstrous enemy she was sent to capture, and by the end of it all, she discovers said mate has two brothers who’re also her mates, and not only were they willing to accept her, they forcefully took her along with them against her will, making Sue dislike and want nothing to do with them.Too bad they were stupidly hot and utterly breathtaking.Cursed because of the sins of their ancestors— Angelo, Landon and Damon lived as part monsters and part wolves, a deadly curse which would end up taking their lives if they didn't find their fated mate, the key to breaking the curse.

You hate hearing the truth?” He demanded then I felt his large hand settle on my thigh.“I can check right now for you, to see if you’re dripping and making a mess of your little panties.”My cheeks felt so red, it felt like they might go up in flames at any moment from now.“A- are you crazy?” I managed after what felt like ages, while gaping at him as an immense amount of shock went through my entire body.He flashed me a dark grin, his fangs gleaming in the moonlight.“Couldn’t you tell?” He drawled and I let out a huff of disbelief.This man wasn’t just crazy. He was mad. Him and his two brothers.
