The Fake Mate by Lana Ferguson

Mackenzie hasn't had a successful date in months. She's only a year out of residency, and her grandmother's obsession with finding the perfect mate threatens to drive her barking mad, so it should be a small thing when she lies about meeting someone . . . until she blurts out the name of the last man she would ever date: Noah 'The Big Bad Wolf of Denver General' Taylor.

Noah, interventional cardiologist and all-round grump, has spent his entire life hiding what he is - an unmated alpha. But when an anonymous tip brings everything to light, he's left with two choices: come clean to the board and risk his career or find himself a mate. So, when the chatty, overly friendly ER doctor asks him to be her fake boyfriend the same day he's called to meet the board, it must be kismet, right?

Mackenzie gets her grandmother off her back, and Noah gets the chance to prove he can continue to work without a real mate - it's a mutually beneficial business transaction. But when the fake-mate act turns to a very real friends-with-benefits arrangement, lines start to blur, and they quickly realise love is a whole different kind of animal.
