Guard by Ellie Pond

He’s grumpy, and no amount of her sunshine is going to fix him.

Flint Larsen understands what he wants, and it’s not Emma Davis. It’s not her curves, her genuine laugh, or the waves of red hair flowing down her back, begging for his touch. Why would a wolf shifter who wants nothing to do with his own magic want to bind himself to a witch?
Emma is on the verge of getting her thirty-year-old self together. A string of bad decisions has dumped her on her ass, including giving her ex-fiancé the down payment for his house and taking a job as a bookkeeper when she doesn’t do numbers. Finally, she finds a job where she can excel. There’s no time for a hot firefighter who tempts her to make more poor choices.
That is, until he kisses her.
With each shift, his infuriating wolf drags him to her townhouse. And Flint can’t help but turn up the heat once he’s there. Things get flaming hot between them, and Emma realizes Flint isn’t all grumpy ruffled fur. But when danger strikes, he must guard her, fated mate or not.
