Suddenly, I'm really glad that this series only has four books in it. It's starting to get on my nerves. One enemy, lots of drama, four books. I think that's why I like PNR so much, since those are at least different POVs for different books.
I don't think I'll ever be able to completely trust Luis again. I understand why he trapped the Djinn in the bottle, but it was a very stupid thing to do.
