Let me start by saying that, even though I’m not big into vampires, Certain Dark Things was a unique and thoroughly entertaining read. This YA paranormal thriller is told from alternating viewpoints of Atl, a naïve young female vampire who’s illegally entered the vampire-free zone of near-future Mexico City; Domingo, a homeless Mexican teen; and Ana, a tough Mexico City cop.

The tenuous balance between humans and vampires, as well as clashes between vampire families and drug cartels, make for an action-packed story. However, the most compelling aspect becomes the relationship between Atl and Domingo. Domingo’s awkward courtship of Atl is genuinely sweet, i.e., this passage told from Domingo’s POV:

“Yeah. I know how it goes. I used to have a girlfriend but that’s not the case anymore,” he told her because he figured it sounded like the mature thing to say. He was attempting to go for “aloof” and “sophisticated,” like they said in the magazines.

World-building is a tricky thing. It can come across as info dumps, which it does early on in this book. However, by chapter 14 the story totally drew me in, and I didn’t want to leave the world and characters.

Moreno-Garcia has a strong writing style. Though in a couple of places descriptions went on a bit long, making me impatient to return to the story, for the most part the descriptions were excellent; for example, this one about the Mexico City district of Colonia Roma:

It was a place for sophisticated older people and hip young ones, with magnificent trees and faded mansions, a taco stand here and there to remind you it was not quite the Belle Époque and you were still in Mexico City.

The Revenant vampire Bernardino is an UNFORGETTABLE character. I also really liked Mexico City cop/single mom Ana. Armed with knowledge gained from listening to her grandmother’s folktales, Ana is one of the only humans in Mexico City with expertise on how to take down vampires. To give you an idea of Ana’s fiery attitude, here’s how she describes a sexist male coworker: “. . . skinny fucker with his cheap tie and his monumental indifference.”

I appreciated Moreno-Garcia’s subtle characterizations, like this one conveying how Atl begins to open up to Domingo. It’s simple but so effective.

He kicked the can in her direction and she kicked it back.

Lastly, don’t skip the glossary at the end. Moreno-Garcia clearly put a lot of research into the story, and it’s interesting to read about the different vampire species from all over the world, their habits, and social structures.
