Long Howl Good Night by Delilah Devlin

Werewolf Aila Mack is ready to get her groove on during a full moon. Because she prefers to keep her liaisons strictly about the sex, she’s a part-time were-hooker. She’s had a taste of were-domination, but now prefers to be in charge of her own destiny.
Brothers Kynan and Jack Parker are on a mission. When their Dark Mountain clan finds an agency dealing in female werewolves, they aren’t happy learning that women are selling their bodies to satisfy their monthly howl. However, they have to take action once they discover there’s a fertile female in the agency’s stable. Their species is in dire need of breedable females.

Kynan and Jack are given the job of bringing home their mate, but they quickly discover there’s more going on beneath the surface than simply a stubborn female who refuses to be collared. Aila’s tempted like never before, as the brothers, one gentle and one fiercely intense, peel away the hard shell surrounding her Wolfen heart.
