Witchmark, by C.L. Polk

This was… okay. It’s the kind of book where you get the impression that the author loves their protagonists too much to let anything really bad happen to them, which kind of takes any urgency out of the plot; also, the characters all feel like either wish-fulfillment dreamboats or cardboard cutout villains. The protag in question is Miles Singer, a morally upright doctor who works with injured veterans; he constantly fights an internal battle between hiding his illegal magic gift and the temptation of using magic to heal his patients. Into his life comes a mysterious and handsome gentleman; detective work, light romance, and mortal (but not too mortal!) danger ensue.
