I borrowed this book from a friend and finished it in about four hours. It's definitely original, unlike anything I've ever read before. The basic premise of the novel is that "A" lives in a different body everyday, and they have no idea why. It's been like this for as long as they can remember, and A has always stuck to their rule of never drastically interfering with the body's life. A exists as a passenger in someone else's life, merely accessing memories in order to act as the person normally would. However, everything changes when A inhabits the body of Justin, and falls in love with his girlfriend Rhiannon. 
 From there, the story becomes a quest to not only continuously meet up with Rhiannon, but also to convince her that A's story is true. 
 Above all, this is a story of love and obstacles. While the idea of A body-jumping every day is intriguing, they don't really wonder about it. As far as A is concerned, there are no others like them. This story is not a quest to find out the secrets or reasons behind A's existence, it's about facing odds and trying to overcome them. 
 Overall, I really enjoyed reading this. A's voice was very distinct and original, yet still clearly "teenager" and relatable. While their situation was pretty drastic, A's core feelings are very familiar to those who have been desperate and in love. The book also held some interesting thoughts on what it means to be human, and the incredible significance we place on our differences, when humans are otherwise 98% identical. 
 In all honesty, I'm not sure if I will read Another Day, but I'm very glad I read this.
