This is one of the coolest covers I've seen in a really long time! I've been staring at it for a couple of weeks and only just now noticed the profile of the other girl.I was really looking forward to reading this because the summary sounded intriguing and unique. Kat Zhang has done an excellent job of presenting a story that questions what it is that makes us a person. Is it our soul or is it a physical body?This was more Sci-Fi than I expected and I did find it hard to keep track of who was who at times. For example, you might have three physical people in the same room but there would actually be six total - two souls each sharing one body. When the topic of romance came up, I felt a little awkward because how do you handle a kissing situation when both people can experience things but only one wants too? I'm sure this will be explored in future books but I couldn't help thinking that it vaguely reminded me of a Siamese Twin scenario.I do feel this story is well written with a very interesting concept and raises thought provoking questions. While it may not have been the book for me, someone else will love it, I have no doubt!
