Mating Season by Nadia Aidan

Two master vampires, one werewolf in heat, and the primal spell of the full moon - it's definitely mating season.

Detective Collette Talbot is happily overworked and up to her knees in cases. With the busy life she leads, she doesn't have the time or energy to find a mate and settle down to have his pups. But with her mating season just a week away she may not have any choice because when she goes into heat every lycan within a mile of her will be at her door. Good thing she has two sexy candidates in mind that would be perfect to help her out with her little problem.
