Wolf Moon by Emma Dean

Jacob is always the one who eases tension with a quick joke. He’s fourth in the Blue Mountain Pack and finds himself eating lunch at the Pack Bar & Grill almost everyday thanks to the new waitress…
Sage just moved to La Grande from Los Angeles after deciding she needed a change. Hollywood just wasn’t her. When her car broke down she found herself in La Grande, Oregon and for the first time in her life she felt at home. It didn’t hurt the guy who’d fixed her car was super hot.
But what she doesn’t know is there’s a rival pack skirting the borders, looking for weaknesses. Will Jacob be able to protect his human mate from the dangers of the paranormal world?
