Absolutely AMAZING! I have loved all of the Perfect Chemistry series & This one was every bit as good as the others! Each book is so original in its own way. I love how you still get to see how Alex & Brittany and Carlos & Kiara are doing while they are no longer the main characters. The way that the book ended it seems that Simone could right a 4th book if she wanted. (Of course, that might just be wishful-thinking... I REALLY want a 4th book!) Anyone who loves a good romance book is destined to fall for this series. I loved how you could definitely tell in Chain Reaction that Luis is the "baby" of the family. His brothers really want to protect him, not just from the Latino Blood, but from harm of any kind. <3 So Sweet!<br/>
I recommend Chain Reaction for anyone who likes steamy romance, witty sarcasm, and just an all-around great book. :)
