Quick Thoughts: 
 Why are there so many characters? I can't keep them straight at first. Why is Kay sad about Win dying, if Ari is dating him... oh wait, this is Ari's chapter, that makes more sense. 
 The story could have been told much quicker with fewer characters. 
 I hate Kay. I really, really do. 
 Diana is BORING. Her entire character seems to be based on who it is she's hanging out with. 
 I have trouble really connecting with Win and Ari because I've never really seen them as Win and Ari. 
 The book jacket made it seem like there was something a bit more dark and dangerous lurking around the corner concerning Win's death, and the twist was a bit of a let down. 
 I don't feel very emotionally attached to any of these characters. Maybe Markos, with his family angst... but not really. 
 I feel bad giving this book a star rating. Did I like it? I really don't know. I feel kind of lackluster about the whole thing. Pretty cover, though. 
 Plot: 
 Set in a world where you can go to Hekamists, who can cast a spell on you to fix something. There's mental, physical, and luck, and if you want to change one, you're borrowing from another. So, say you want to be prettier; you might be a bit less lucky, or a bit dumber. 
 Enter a million and one characters you have to keep straight in your head even though none of them are that interesting. There's Ari, who's boyfriend Win, just died. She casts a spell to forget him. Then Win gets his own chapters from beyond the grave, you know, because. There's Diana, who seems kind of just like a throw away character. Put there as a place holder so we have an excuse for Kay. Kay is an annoying hanger on who causes a lot of the books conflict. There are the Water's boys, there's Markos and Cal and a few others you don't really need to know but are hovering in the background. Then there's Echo, who probably has the most interesting story, but she doesn't get much page time. 
 We follow the teens as they deal with the death of their friend, Win, and we see how they handle it. I really liked the world Lehrman built, and I felt like so much more could have been done with it. I thought that Ari was going to join Echo's coven, to save her mother and then Diana would have to, because she wants to help Ari, and then Kay would have to, because she does everything Ari and Diana do, and then Echo and her mom would be safe. Then that whole plot line could be explored, them needing to move to avoid detection, etc. I guess that's how I feel about this book. Unfulfilled. There were so many ways this book could have gone but it was too scattered and too focused on things I didn't really care about, while amazing things were going on just to the side. So, I didn't dislike this book, but I don't know that I liked it either. I'm hoping this is a stand-alone, because that at least, would be refreshing.
