Runt of the Litter by Isabelle Hemlock

Avery Gallagher is a shifter who doesn’t fit in anywhere. He doesn’t look like his lumberjack twin brothers do, nor has he managed to phase once in his twenty-something years. He doesn’t seem to belong in any world, neither the wolf kind, or the human kind. Meanwhile, Riley Connolly is a pureblood werewolf without a mate.

Surrounded by more than her fair share pick of anybody, she hasn’t managed to sniff out the one who will make her happy. And she’s beginning to think she might just never find the one meant for her. That is until one day, when their worlds literally crash into one another . . . and though Avery isn’t so sure he deserves to have a pureblood mate, soon enough he’ll fall under Riley’s spell. Though that’s only the beginning of their problems. Because they still need to get everyone else onboard, too.
