My Alpha Mate

Madisyn Boyce is funny, smart, outgoing, gorgeous, energetic and athletic. She has everything she could possibly want. Loving Aunt, five older brothers, a twin and an older sister. She's also, mated to the Alpha's only son ,Demetri McCloud, who is going to be the Alpha in a weeks time.

Demetri McCloud is the Alpha's only son or so he thought so. A day after he becomes Alpha his mom and dad tell him that he has a twin brother, River. They were expecting him to be angry for not telling him. He's just the opposite, he can't wait till he meets his twin. When they finally meet he thought they would get along great and they did. Until, Demetri introduces him to Madisyn. He knows they will get along great, but River starts acting weird around her. Then it all clicks. River wants Madisyn to himself and he'll destroy anyone who gets in his path. Little does River know that Madisyn is the sister of six very over protective older brothers and a very, very, very overprotective mate.
Brother vs. Brother, who will win?
