Soft Flannel Hank by Eliza MacArthur

If you were ever a Twilight person and you thought, "hey, what's the deal with Bella's dad?" this book is for you. Hank is a middle-aged man deep in the throes of depression and ennui. Esther, a witch on the run, rolls into town like a hurricane and upsets his quiet life. Hank's natural protective instincts--and his attraction to Esther--take over, and he's waking up from his boring but steady life. But Esther's secrets will put them both in danger if they can't work together.
