This is pretty much exactly what I wanted from it! The first half was more narrative and really flew by for me. Definitely plot based, because I can't remember a single detail about any of the characters or even their names. While I enjoy science, the science writing got pretty dry as the book went on and made it harder for me to want to pick up the book. It's all good and true and whatnot, but as I was nearing the MCAT it just felt like more MCAT reading and not science fiction , which may or may not be my fault for the timing but I didn't want to pick it up as much. Even so, highly enjoyable, (mostly) fast paced, and more than a little eerie.
