Alison was not my favorite character in Boomerang. I was a little hesitant when I realized we were going to be hooking her up with Adam. I liked Adam a lot, though he was pretty much the stereotypical tragic hero. Alison was okay, but I just didn't care for her like I did Mia. I understood where she was coming from, I guess, but all in all, she just was kind of boring. I'm glad she got to work through her issues and all, and come to terms with her past and make nice with everyone but, meh. MOST relationships that end don't end up with the exes being friends so I don't know why this was so important. 
 The book was predictable, reading much like Boomerang did. Was I the only one hoping that Alison and Mia would get paired up at the retreat instead of Adam and Alison? I understand the WHY of Alison and Adam, but it could have been a huge insight and added a lot of depth to see Alison have to interact with Mia instead of Adam. Overall, it wasn't a bad book, and I'm hoping for more from Skylar and Grey's story.
