Well that book was just so stinking cute! Molly Peskin-Suso is one of the most relatable characters I've ever had the pleasure of meeting in a story. Molly's were like mirrors of my own-her awkwardness around new people (especially around boys) is so much like me it is INSANE. I mean, Molly is basically me! Her fears about being a late-bloomer, while a tad bit ridiculous seeing as she's only 17, were also quite understandable as she watches all her friends, and even her sister, find new and exciting relationships while she struggles to get a handle on crush number 26. I really enjoyed reading Molly's story and watching her grow more comfortable with her changing circumstances and with herself. 
 This book is pretty much the perfect coming-of-age story. My only complaint (and the only reason I'm not giving this 5 stars) is because of Cassie, Molly's twin sister. She filled me with rage more times than I could count. Some of the things she said to Molly were just NOT okay. And I understand that a sibling relationship is not all sunshine and unicorns, but Cassie was downright cruel at times and then would have the nerve to turn things around on Molly to make herself feel like the victim. I just wasn't happy with that. I enjoyed the diversity Cassie brought to this novel but I did not find her character likeable. 
 Aside from my dislike of Cassie, I really really liked Upside! I especially loved Middle Earth Reid and his adorably nerdy personality. There were so many cute moments in this book that I will definitely look back upon and smile thinking about! While I didn't have Simon vs. the Homo Sapiens-level love for this book, I still enjoyed this immensely!
