Chain Reaction By: Simone Elkeles

The final book to the Perfect Chemistry novels... It was perfect. This one is about the last son Luis, the final Fuentes... Anyways, the book starts off with the wedding of Alex to Brittany (I died from happiness) and Luis is 15. The love interest is Nikki Cruz, a Latina girl that denies her Mexican heritage (this made me sad... I mean come on. Embrace your heritage). They hit it of... By Nikki kneeing Luis in the balls. Perfect... It then flashes two years in the future, Luis is now 17 and is living in Chicago again. Luis Fuentes is the good boy in the family, not expected to do anything stupid, he has hopes and dreams, everything is good for the youngest Fuentes. Now Nikki is very bitter, she at 15 got pregnant with your boyfriends child, whom broke up with her making her bitter, then to top it all off, looses the baby. So she's bitter and really mean... And she is Luis's love interest. Now that Luis is back very thing is going smoothly, the Latino Blood is gone because the  main guy, Chuy is in jail because of Alex. But Luis being an idiot, ends up joining the Blood stuff happens, and turns out his REAL dad was Hector Martinez!! That was a huge shock... Anyways, everything turns out ok in the end.  :3
I loved this book!! It was the perfect ending to all the Perfect Chemistry novels, and this one was a bit of a shock at the end, but absolutely perfect. Why must the Fuentes boys be so sexy !!! :'(   So this one was just amazing, Luis was just so loveable and cute, as it said in the books with was the more "innocent" one... Not really... ;)  Nikki on the other hand really REALLY annoyed me. I understand that she got pregnant at 15, lost the baby and her boyfriend on the same day, but she took her bitterness way too far. I mean she was waiting for her friend to break up with her boyfriend saying "All boys are the same... Boo hoo for me my first and ONLY boyfriend left me pregnant... Then dumped me..." She really truly annoyed me. And how she judged Luis right away, for him being Mexican, living on the poorer side of town, and being friends with some of the gang bangers, sucky... Other than that I loved the series, and this one was the best. It had more background on the Fuentes family, and showed Alex and Brittany as parents, Carlos as a military man getting ready to propose to Kiara. And the epilogue was just perfect, it showed all of them together when they were older, with their own kids. It was just adorable.

One thing I noticed, all the boys had a different thing to call their girl. Alex: mamacita. Carlos: chica. And Luis: Chava. It made me melt.. :D
