Sweet Evil is not your average angel book and I loved Wendy's take on light and dark angels. Wendy paints a very clear line between good and evil, light and dark, and her character Anna has to struggle with both sides because she's caught in the middle. Anna is a pretty decent character, not as tough or snarky as I like them, but not weak or timid either. There is definitely a dark theme to this book and although not the gripping page-turner I was hoping for, it's still a great read. 
 Kaiden is definitely one of those hot book boys you can't get enough of. Add in the fact that he's part of a band, and he's got those sweet angelic powers, you'd be one of the few that could resist him. At least, that's how he's portrayed in the book. Personally, I could've used a bit more detail into his mind and background and frankly, there wasn't enough depth in his relationship with Anna for me to believe how strong their love supposed to be. It seemed more like lust to me, which, considering his character, is I guess how Wendy wanted it to be?! Their love definitely isn't an epic romance or a sweet one, and I really hope it develops more in the next book because I'm getting the attraction and lust, but not the love and passion that I was hoping for. 
 I think, if anything, I liked the slew of secondary characters and how they gave me a glimpse of each type of angel there is. We deal with the fallen angels in this book and they basically follow the "deadly sins" logic, with Dukes representing each (lust, greed, gluttony, etc). I liked seeing all that play out and although you don't see much of the Dukes themselves, you get to see their children, which is way more fun anyways. My favorite would have to be Kope, because he's so different than the rest and I really liked his interactions with Anna. 
 I'm very interested in seeing where Wendy takes this story and hope that Kaiden and Anna develop their relationship more. The struggles they have coming seem pretty intense and that ending was great. I can't wait for Sweet Peril.
