I don't like the feeling of being poised in suspense to find out whether the twist is obvious or strange. There are two main characters with two different understandings of what their reality is, and I got far enough to know I didn't care who was right, if one or both of them are actually dead, or if it's some additional permutation I didn't think of.

The island sequences were pretty cool, the world is an interesting dystopia, and I like the audiobook narrator. This just wasn't a story I like.
