This was such a great idea! There are lots of science fiction/fantasy books out there for Young Adults. And I can't put my finger on what made this book so different, except to say that the feel of the book was just...new! Lucy seemed like a very normal, down to earth (haha) girl. Until she meets a very different kind of guy, and everything changes. There are things going on in the universe that are beyond imagining, and Lucy is right in the middle of it. Now she has to rely on this strange and beautiful boy to help her. Extremely intense at times, and very romantic. This book would be perfect for a preteen/teenager. I think it may be a little young for some adults, but the storyline itself was good enough for me to really enjoy, and memorable enough for me to write this review two months after reading the book, because I couldn't stop thinking about it. I'm hoping for a sequel!
