I went into The Theory of Everything hoping that I'd find a charming, contemporary read that would make me smile. Of late, I've been reading a lot of paranormal books, and was kind of tired of them so wanted something that would do a complete 360*. Thankfully, that's exactly what I got from this book: while having quite a lot of scientific talk - physics, to be exact - I was utterly charmed by the main character, Sophie, and the cast of characters that surrounded her throughout her journey.This book was very different than anything I'd ever read. Sophie, our main character, sees things that others can't see, which obviously causes problems for her and her mother. Her "mental illness" has resulted in suspensions/expulsions from school and several moves to different locations where her mom hopes they can start over with a clean slate. Having settled this time 50 miles north of Chicago, Sophie is hoping that her "episodes" will stop and she can finally have a normal life. While in her new town of Havencrest, Sophie befriends an absolutely amazing character named Finny, develops a crush on Kerouac-reading Drew, and gets a visit from her shaman panda, Walt.Part of the craziness of this book is the fact that the reader isn't really sure if Sophie is indeed hallucinating or if she's actually traveling to various parallel universes. Deciding that she cannot keep living like this, Sophie and Finny travel to New York, where Sophie hopes to speak with her father, who suffered from the same problems. What results is a cross-country journey into personal introspection, sort of a road trip without the road. Throughout it all is Finny, possibly the awesomest best friend of all time, who - instead of telling Sophie she's crazy - decides that this is one heck of a journey and that he will go with her every step of the way.While Sophie's journey is equal parts strange, amusing, emotional and downright heartbreaking in places, it was actually Finny who made this book for me personally. He had all of these really great lines, and just really seemed to get Sophie and what she needed each step of the way. He was equal parts physics-obsessed and happiness-inducing, not only for Sophie, but also for the reader. Honestly I don't think this book would have been half as good as it was without him, and I can only wish I had a Finny of my very own. Seriously, you should read this book just for him!The Theory of Everything is a fantastic contemporary read with a twist. There is a lot going on in this book, from Sophie's episodes, to trying to fit into a new place, to dealing with family secrets, drama, and first crushes. If you're charmed at all by the synopsis or the cover (seriously, this has the perfect cover!), then pick it up because I don't think you'll be disappointed. I had a ton of fun with this one, and would definitely recommend it!An e-galley was provided by the publisher via NetGalley in exchange for an honest review.***To see more of my reviews, please visit me @ Read and Reviewed!
