I absolutely loved this YA realistic fiction book by Susin Nielsen! The title and cover of We Are All Made of Molecules drew my attention, and then I really couldn't didn't want to quit reading once I started. I listened to this book on audio--a nice choice as it is told from two points of view, Stewart's and Ashley's, and two different readers shared the narration. I generally "read" my audiobooks when I'm exercising, so this book was good for me intellectually and physically!Stewart is a 13 year-old kid who is highly gifted, but a bit inept socially. He lives with his dad, a producer of the local TV news show, and his cat Shrodinger, since his mother died after a long battle with cancer two years earlier. Ashley is a 14 year-old girl "at the top of the social ladder" at her school. She's nowhere close to a good student--except in home ec and P.E.--but she has looks and great clothes, and a group of girls who hang on her every word. Ashley's mom is the anchor woman for the local TV news, and everything would be perfect for Ashley, except that her parents divorced two years prior, when her dad came in one evening and announced to the family that he was gay. In her attempt to keep up appearances, Ashley's never told anyone about why her parents split. Now, Stewart's dad and Ashley's mom have gotten close, dated, and decided to combine their families. Stewart is thrilled; Ashley is anything but. Both of them have a lot to learn about people who are different than they are, and a lot of common teenage hurdles to face. There are a lot of great lessons for readers of We Are All Made of Molecules, and I would highly recommend it to most middle and high school students as a fast, engrossing, and thought-provoking book
