Sweet Filthy Boy was definitely an enjoyable read. While I'll admit the middle of the book is pretty mild and the main character tested my patience at times, the beginning really grabbed my attention and the ending was just plain sweet and romantic. Both of those things, coupled with CL's entertaining writing, made me really love this story. 
 Like I said, the beginning of the book really grabs your attention. Mia and her friends just graduated from college and are spending an epic weekend in Vegas to celebrate. I loved every minute of these first few chapters and I seriously couldn't put it down at first. Watching them live it up was great, but seeing them meet Ansel and his friends, learning of all the crazy crap they got themselves into, really had me glued to the pages. It is definitely as crazy as you'd expect from drunken escapades in Vegas. I enjoyed getting to know the wild sides of Mia and Ansel, but also getting hints of what lies beneath. 
 However, after Mia manages to get herself to Paris, things turn awkward and dull. Mia definitely has some issues she's working through, trying to figure out her what to do with her life when the one career she's always wanted goes out the window. Not only that, she definitely has issues with letting herself go, getting out of her comfort zone, and expressing herself, either through words or actions. She definitely bugged me quite a bit with how she acted towards Ansel and even during those times when she pretended to be someone else and let go, it still felt forced. This went on for awhile. 
 I did like joining Mia in Paris though. She saw a lot of sights and it was just great being able to visual that magnificent city. Also, Ansel was definitely a great male lead. While it sucked that his work took him away from Mia for much of the time, (which I thought was lame because how can these two really get to know and fall for each other when he's gone most of the time and when he is there, he's tired and cranky?!) those moments when they were together, while awkward, was still pretty sweet. And I especially loved when he spoke French to her. Swoon! 
 I also loved that CL was able to surprise me two-thirds of the way in, which doesn't happen often. And it was a great and twisty surprise. It definitely gets these two moving in the right direction towards the end, when you can finally see Mia's character development really shine through. I was definitely pleased with the ending and really loved watching these two characters fall in love. I seriously can't wait for the next book!
