This review originally appears in full at http://bellesbookshelf.blogspot.com/I was initially a little concerned that Rules of Attraction would feel like copypasta of Perfect Chemistry, but I needn't have worried. Sure, the two books are structurally and thematically similar, but the characters are completely unique. Carlos may be related to Alex, but the two are quite different. Carlos is even angrier at the world than Alex was, and takes his emotions out on those around him. As a result, he comes off as quite, well, douchey for a big chunk of the book. Of course, he's a good guy deep down; his sweetness just takes a little longer to surface than it did in Alex's case. Which makes him pretty amusing, but also incredibly frustrating and hard to warm to at first. It's OK though, coz his hotness in the second half of the book more than makes up for it.What I liked most about Rules of Attraction, though, was not actually Carlos - it was Kiara. She was a bit of a dag, but I loved that she was smart, had unique interests, an awesome gay best friend, didn't care what other people thought of her and took no crap - especially from Carlos. She gave as good as she got, and it was totally hot. Plus she has an incredibly amazing family who were so fun to read about. At first I was like, are these people for real?! Taking in a gang member the same age as your teenage daughter is not exactly a smart move, when you think about it. But when Kiara's dad's background is revealed, it all makes sense. I loved the way they all looked after each other and enjoyed spending time together. Hello, Family Fun Night? Adorable!The chemistry between Carlos and Kiara wasn't quite as explosive as it was between Alex and Brittany (for me, at least), but it was still pretty fiery. I loved the glimpses we got of the older couple, too; they're so loved-up for most of the book and it's great to see them going strong. There was one plot twist that kinda threw me off, but thanks to the cheesetastic epilogue in Perfect Chemistry I knew everything would be OK. There's another extra cheesy epilogue in this installment, and I gotta admit I enjoyed it. I do love me a happily ever after.
