Renee's Mates: A Paranormal Reverse Harem Romance (Churchill Polar Bears Book 3) by Shelley Munro

Four brothers seek one woman. Mission: revenge.

Soldier Renee Paulson and her best friend witnessed a murder. When her friend dies in suspicious circumstances, Renee flees to a secluded town. A helicopter pilot, she flies tourists over the tundra and delivers supplies while keeping a low profile.

Like most werewolves, the Taktuq brothers are family oriented. Their younger sister is adamant Renee had an affair with her soldier husband, and they promise to investigate. Exhaustive research leads them to the Arctic town of Churchill. Renee Paulson or Renee James, the name she goes by now, is a sexy surprise. She’s solitary and wary, and it seems she is their mate. Perturbed, the brothers push on with wooing and romance while conflicted by their obligation to their sister. Peeling away Renee’s protective layers reveals a desirable, intelligent woman—one they wish to keep in their lives.

When an assassin catches up with Renee, the Taktuq brothers embrace their wolves to save her. They’ll do anything to guard their mate, even protect her from their sister.

Contains a strong, plain-Jane heroine, four werewolf heroes with attitude, lots of secret sexy times, a pissed younger sister and an assassin with a big gun.
