Fifty Feet of Trouble, Paperback/Justin Robinson

Being a private investigator ain't all it's cracked up to be--especially when you spend most of your time looking for missing kids and trying not to get turned into something that goes bump in the night instead of making time with femme fatales. But hey, it's a living. And there's never a shortage of work for the last human detective in a city of monsters. Right now, Nick Moss has three cases: tracking a missing girl, a young woman, and a toad, not necessarily in that order. The deeper he gets, the more troubling connections he finds--to his past, to some of the most dangerous monsters in the city, and to places he hoped he'd never have to go. All Nick knows for certain is that he's in trouble. Fifty feet of it.
