Her Beta by Fiona Davenport

Driving a pregnant member of his pack to the hospital while she was in labor was an experience Leyton Vetle didn’t want to repeat. But then her pretty nurse turned out to be his fated mate, and he knew that he’d go through the knuckle-whitening ride a million times if that was what it took to have her by his side.
Evette Loughty had no idea shifters existed, let alone that she was the fated mate of The Wilderness Pack’s beta. But there was no denying the pull she felt toward Leyton. Too bad the timing was awful since she was leaving for a new travel nurse assignment the same night.
