Unspoken by Sarah Rees Brennan
Can I just say, I loved this book! I had heard good things, knew it would have a major cliffhanger, but WOW! I loved the story, I loved the characters, I loved the sarcasm, I loved the romance, and I hated the ending (cliffhanger!) and I cannot wait to read the second book, although I hear it's ending is even worse that this one was!
