Ho-ly crap. I loved this book. My mind is reeling and I might have to blurt out a review just to straighten my head out.-Although I know it's not very usual, I'd like to start off my review with a bit of a personal confession. For as long as I can remember I've had a strange relationship with music. I'd like to say that I listen to music, but listening would be the wrong verb. I experience music. I never knew there could be a name for it until after I read this book - I always thought synesthesia had to do with colors and numbers/letters, but not sound. While I was looking into it, and saw that someone referred to it as music having a three-dimensional equality and feeling I almost had tears in my eyes: that just made so much sense. So, thank you, R.J. Anderson. Not only did you write a breathtaking book, but..now I think it may have a name.Alison Jeffries is almost just like any other sixteen year-old girl. She attends high school, she has friends, an occasionally annoying little brother and... she experiences her senses in a way that is difficult to put into words. Sounds are vivid and colorful, numbers and letters have associated emotions, and words can sound off. The almost isn't necessarily because she experiences these things, it's because one morning Alison woke up in the psychiatric ward of a hospital without any idea how she got there. Until it all starts coming back.Ultraviolet is a book that I wish I had read long, long ago. It's a book that was riveting from the very first paragraph and held my captivation until the last sentence. And it's very much a book that I think people should read. I have to say that I loved Alison as a character in part because some of me related to her, but mainly because she was just a breath of fresh air. In order for this sort of storyline to be pulled off so much about it has to go right to evoke the feeling of believability for what she was experiencing. And it did, and it worked so incredibly well. Because the majority of the story took place with a young adult's psychiatric home the feeling of the story was pressing and urgent and served as the perfect backdrop. The cast of secondary characters were invigorating and vibrant from the unsure-of-how-to-feel-about-him Dr.Minta to all of her fellow residents and even her mother.And, seriously, just when you think you know what's going on - you have no idea. Not everyone could pull a twist like this off and integrate it so well into the story, but she did and I believed every part of it. I've seen that some people were iffy on the ending, but I'm not at all one of them. I loved every nook and cranny of this story and I'm hard-pressed on my book buying ban not to run out and order a copy for myself right now.If you like a book that feels like a contemporary with a sense of urgency and something slightly more then this could be a book for you. If you like a mystery or a fast-paced book of amazingness, this book is also for you. If you're like me and you can see/feel music and need a name for it, this book is most definitely for you.This ARC was received from Orchard Books via NetGalley in exchange for an honest review.
