Romeo Spikes by Joanne Reay is part mystery, part police procedural and part epic struggle between good and evil. Detective Alexis Bianco works for SCURO which is a clandestine group that handles supernatural crime.
The book introduces a group of evil supernatural beings called the Tormenta. They push humans toward suicide. As their victims die they suck the remaining "life span" out of the body by kissing them. Bianco and her partner Lola - a renegade Hunter - track down Tormenta and kill them.
There's a lot going on in this book. The "Brothers" who train the Hunters have their own rules and they don't always fall in line with the "good" side of the good vs evil struggle. For a first novel, Romeo Spikes is quiet accomplished. It's a good story with good pacing. My only nitpick is that the traitor inside the Brothers' organization is a bit too obvious.
I received a review copy of this book.
