This was a well written mystery but has a lot of violent action. The owl is a justice vigilante and he is crazy. Nothing will stop him.
Many thanks to Brash Books and to NetGalley for providing me with a galley in exchange for my honest opinion.

OWL: JUSTICE NEVER SLEEPS introduces a new type of Noir protagonist. Alexander L'Hiboux (a French surname which translates to "owl") literally never sleeps, due to a physiological condition. He literally never sleeps. Now from inability to sleep to vigilante justice and homelessness may be a leap, but nevertheless this is Owl's way of life. The author does a complex job of unfolding his protagonist's character and backstory so that the reader is continually surprised; even after the first book we don't "know everything." This is a multi-layered individual indeed.

OWL: JUSTICE NEVER SLEEPS contains a high violence content, since Owl is, as he terms himself, "a killer," and his reputation is such that most bad guys don't want to mess with him. Of course, there are still some that do, and in this novel, the bad guys are seriously evil. Some of this violence will likely upset sensitive readers. Be aware that this is Noir so there will be violence and profanity and nasty characters as well as a "good guy" who is not really "good" but does have his own code of honor, kind of like a renegade samurai, one might say.
