A Mate for Orion by Selena Scott

Little do they realize, they’re falling in love on borrowed time.
Something is up with the shifters in Portland, Oregon. And if there’s one person who’s going to get to the bottom of it, it’s Diana Paul. As the executive director of a center that offers all sorts of services to shifters, Diana is extremely protective of her clients. All except for one extremely annoying -extremely attractive- wolf shifter named Orion.
Orion is used to taking care of his siblings, he’s been the protector who’s been doing it his entire life. Maybe that’s why Diana’s take-no-prisoners attitude draws him in so quickly. She doesn’t need anyone to take care of her, she kicks ass and takes names. Orion didn’t even realize he was looking for a woman like her until he met her. Now, if only he convince her to date a client…
As Diana and Orion get closer and closer, they begin to notice the strange behavior of someone in their lives. Little do they realize, they’re falling in love on borrowed time. There is something dangerous barreling toward Orion and his siblings and Diana might be the only one who can stop it.
