Stay Dark is the start of an urban paranormal fantasy series where vampires, or "dwellers", exist in a social structure, but hide from humans. Neve was turned by an unknown person when she was close to dying and was left on her own. She is aware of the various vampire factions, but she chooses to stay away from them, making a living as a PI. Her way of dealing with her new life is to help humans being attacked by vampires and live on blood donations rather than killing people.
Unfortunately, one of the people she saves turns out to be a serial killer who goes on a killing spree shortly after. Guiltridden by this, Neve is deadset on finding and stopping him. Though skeptical at first, she decides to team up with the police detective assigned to the case. But Neve isn't as good at hiding as she thinks, and soon both humans and other vampires are aware of what she is. Nothing good can come of that.
I wasn't overly impressed by this book. It doesn't stand out in the genre, and changing the species name to "dwellers" doesn't make them any less vampire. The enemy isn't necessarily other vampires, but rather the human government, which again is nothing new in paranormal stories.
The dwellers are supposed to live in factions, not alone, and are governed by "headhunters" who ensure there aren't too many vampires in the world. Sounds fancy in theory, but upholding it in real life must be difficult, which is probably why the author doesn't give many details on how this is enforced. It gave me "Volturi" vibes from Twilight. The factions also act similarly to mob gangs, and the internal power struggle is evident.
Another thing that gave me pause was the instant familiarity between the characters, especially Neve and Marek. Complete strangers, but after having met only once or twice, they are infatuated, trusting, and act as if they have known each other for years. Neve's relationship to Inez is also similar, marked by almost instant loyalty and trust. As a reader, that was hard to buy into.
I also missed character building and development. After reading an entire book, I struggle to describe the characters' personalities, except for their moral compass.
The book wasn't bad, but it didn't give me much, personally. I will not continue with the series. I received an advance review copy for free, and I am leaving this review voluntarily.
