My Vampire Mate

Alpha werewolf, Aaron Thomas, rejects his Omega mate, Kingston Martin, on his mates birthday not because pack prejudice but because he's in love with a female Beta, Marisole Potter, and he doesn't believe Kingston could handle the pressures of being the Luna of the pack. Right after the rejection, Kingston and his wolf Lucifer loose control of their magical abilities and run off to have time to deal with the rejection in private. He's later found by a vampire who explains something about Kingston that no one has been able to tell him so far.
