The Witch is Back by Sophie H. Morgan

Overview: Love is a hex of a thing. Former childhood sweethearts fake a relationship in this charming, witchy romcom.

There’s nothing wrong with being a wallflower. Not to Emmaline Bluewater, anyway. Emma may have been born into witch society, but her days of trying to fit in where she doesn’t belong are over—they ended seven years ago, when the man she’d hoped to marry left town without a word. She’s much happier now, living a delightfully mundane human life in Chicago and running her bar, Toil and Trouble.

Until Bastian Truenote walks through the door and announces that he wants her back.

Bastian had his reasons for leaving—even if he can’t tell Emma what they are. Now, to win Emma’s heart, he’s got to face down an adorably goofy dog familiar, a best friend who’s all too eager to hit him with a carefully aimed hex, and a woman who’s far from the meek witch he remembers.

Magical contracts aren’t easily broken, but as far as Emma’s concerned, not even a marriage of convenience will have her falling under Bastian’s spell again…
