I was approached on Goodreads and asked to review this book in return for a free copy of the e-book. This starts out as the story of four vapid seeming frenemies on spring break from college at a resort in Mexico. I was not impressed - i'm not a fan of Gossip Girl. The writing, the dialogue, was all poor and seemed rather ridiculous. Did a grown up even write this? I just started laughing, and then I realized that might be the point. In the blink of an eye, it switches over to a story about drug running, and escaping a cartel. Only, kind of not really. It's not a spoiler to say that these girls, before only concerned with the perfect hair and clothes and making sure their skirts are hiked up enough, become cold blooded killers. Not only that, they do it WHILE still being concerned with all those things. They can kill someone, then complain about their hair, or fix their eyeliner. The whole thing reminded me of a Grindhouse movie. We have gorgeous women in tiny, skimpy clothes, drinking a lot, and then randomly offing someone with a gun or a MACHETE! They could give the Mad Men cast a run for their money with all the smoking and drinking that goes on! It was hilarious, violent and gory and I enjoyed myself! I'd love to see this made into a movie, with girls teetering on too-high heels and too many shots, as they take out yet another cartel member. In the end, I enjoyed it. Fast-paced and just weird. If you're looking for a teen sort of vacation book, or don't like violence, skip it. But if you like campy action things starring hot girls (even unlikable ones) and bad dialogue, go for it.
