This was a fun, short book that can be read in one sitting. Unfortunately, I though it was too short to get to know anyone except Kate, the main character, too well. But that's okay, it's entertaining and funny and Greg is actually quite likable.Zach is vile! Yuck. I must say I was a tiny bit annoyed at Kate for wanting him back after that first scene, let alone the rest of the things he did, I was just about to smack her on the head when she finally came to her senses. Then she left them again.It's a fun concept though, something I've thought about once before when I read freakishly specific horoscope for the day. What would it be like if you followed everything it says? Well, Kate does exactly that, a little too literally, but it all works out for the best.So yeah, I liked it, it gets a 3.5 from me.
