(View this review on My Library in the Making.)Antithesis didn't turn out the way I'd thought it would. That blurb is so vague, so misleading, that my jaw dropped when I found that my theory about this book couldn't be farther from the truth. And if you're wondering, I'd assumed this book was psychological, that Gavyn was crazy. She wasn't.Now, before you stick around any longer, I'll tell you that I plan to be as vague as possible in this review and keep the air of secrecy that the blurb-writer intended. Let the book surprise you.The plot kicked off nicely right in the first chapter, and my brain was just like "WTF is happening?!" Like I said, utterly wrong theory. The sci-fi element *hint hint* was a big surprise, and one reason why I really enjoyed Antithesis was because I haven't read lots of books about said sci-fi element. I do believe it's becoming quite the crazy lately...Gavyn was a likable character. Her handicap made her unique, not bitter. She was actually quite the normal teenager with worries, insecurities, raging hormones, and a ridiculous bucket list. But one thing I disliked about her was how she constantly ranted about her red hair as if it was a handicap like her one-armed-ness. I'd love to have red hair!What is it with fictional guys named Liam? Each one I've read so far have all been smart, hot, and a little bit naughty—written to make me insane, I think. But Liam's not as memorable as his relationship with Gavyn. It's easy to find swoon-worthy boys in books, but swoon-worthy couples? Nuh-uh. These two were so hilarious and awkward yet still sexy and sweet together. I may have snorted and giggled a lot.Gavyn and Liam's crazy adventure made for a fast-paced, unputdownable read. I have to admit that the climax felt like a cop-out, but the ending sure has me up for a sequel if there'll be one!MY FAVORITE PART is the shower scene! Sweet baby Jesus (hmm, JLA reference?).
