This is the kind of book that I can't really comment on, not because I don't remember it, but because it was so short that you can't write about it, but I'll try. 

Lana was an extremely complex and complicated character, perhaps too much, but that made her so excellent. Her thirst for revenge, perseverance, and brutality were all things that added even more to this story. Logan wasn't stupid, he really wasn't, but he let himself

and will let himself

be led by the nose like everyone else, but that doesn't make him bad. He, too, has had difficulties in life, and he still tries to pursue the good and not the bad. 

Their relationship was kind of insta-love, to be honest, out of the air, but it still worked — which is a big word. I'd say they're perfect for each other (as far as a serial killer and a detective can be). 

Well, it wasn't much of a plot, but I didn't expect anything else from a 130-page book, but it brought that dark atmosphere. The pace was good, but maybe a little fast.
