Until the last chapter or so, this kept me turning the pages so quickly that I had planned to give it a fourth star. Then, the ending, such as it was, happened. I found the "revelations" about Maggie's character to be so difficult to believe that my enjoyment of the story was damaged, and the non-ending involving the main character only made that worse.
The "noir" aspects of the story really weren't. Yes, bad things happened. Yes, the main character was so damaged by what happened to her as a child that her behavior still hasn't recovered as a teen. That's not really noir...that's usually a brand of crime fiction, and while there is an ongoing mystery about Maggie's death, it's not really dealt with as a murder mystery. The "noir" label kept me guessing, to the point where I kept looking for clues, but they just weren't there for the most part. The subplot involving Luke and his photos finally made sense, but even so...I just couldn't like Jude, the main character. Yes, the story only takes place over the course of a few days, but the story suggests that there's been no character growth on her part over the course of several years, and she's just a jerk in ways that aren't justified...and all of her "friends" know it, and call her on it, repeatedly.
Was the book worth reading? Sort of, because there were some really good parts. Not a great book, though, because of too many characters that didn't seem like they were worth reading about.
