Received this as a First Reads giveaway which I entered because I liked the plot description given. A very fast read; no thinking caps required here. You're plunged right into the story on the first page with no set up, which is a good thing in thrillers. Plenty of action and a unique twist on the cartel theme with Brujas and black magic prominent. No spoilers but I liked the ending; not what I expected but it fit the story well.
I would have gone 4 stars on this if the writing style was more to my taste. I'm sure there are plenty of action fans out there who will love this, but for me it seemed geared to attract teenage boys. I almost expected to see captions during some of the fight scenes (you know, like from the old Batman series -- "BAM" "POW" "CRASH"! I'm not a prude and I do read books with adult themes (you would hope so), but the sex scenes made me uncomfortable. Definitely not geared to a woman's perspective, with all the female characters, other than Powell's angelic wife, being complete whores who will do anything with anyone for money. Kind of James Bond, but sleazier.
Short and sweet: If you want a fast-paced action thriller and you're not picky about the prose, go for it.
