Cinder, by Marissa Meyer
Oh, I loved this book...it took me two days flat to read it. This modern, science fiction retelling of Cinderella is a reminder of why I love YA literature and reading. Great plot, totally believable and relatable characters, just the right amount of description, and great originality - all together, they make one hell of an enjoyable read. I'm so glad Meyer turned this into a series, and greatly look forward to reading the second and third installments.
