Ladybirds by R. Raeta

Miracles don't come free and words are binding...

His miracles have a cursed edge, but he’s not the villain Sara expected. Still, she’s not exactly thrilled about being stuck with a centuries old ghost with a flair for the dramatic and a nasty habit of pushing her buttons just for the fun of it. With his penchant for boredom—and the fact that she’s the only one able to see and hear him—he’s about as common as her shadow and as welcome as mold.

Even if he is pretty handy in her British Literature class.

An enemy to lovers romance.
