Samantha Ruiz has a freak gene that makes her turn invisible, or ripple. She can't control it, and it's getting worse. Afraid of becoming a lab-rat, Sam keeps her ability secret, until fellow runner Will Baker sees her vanish into thin air. Will promises secrecy and help, and Sam begins to fall in love.
Together, the two discover there are worse things than being a scientific curiosity. Someone's been killing people who possess Sam's gene. A mysterious man from France sends letters that offer hope for safety, but also reveal a sinister connection with Nazi experiments.
The more time Sam spends with Will, the less she can imagine life without him. When Sam uncovers secrets from her past, she must choose between keeping Will in her life or keeping Will safe.
I try not to review a lot of YA books, because I tend to have rather strong reactions to them, either I love them a lot or I hate them. I was really happy to find that I really did enjoy this book from beginning to end.
To start with I would say the writing in this book is really good in terms of flow, so readers will really enjoy the experience. The book just had a really nice kind of pace to it, I never felt like I had to rush to finish it (and then of course miss out on things because I read to fast), but I also didn't feel like the book was dragging or getting boring. So it was a nice pace, especially for the YA crowd.
Another thing I feel like i have to mention is that the dialogue is pretty good. A common problem I have found in YA books is that you have a bunch of adult writers trying to write to either appeal to a younger demographic or to actually write a younger character, and it doesn't always come off right. I have to say this was pretty good dialogue. It was enjoyable, easy to follow, and didn't feel like it was trying to hard.
As for the characters, I enjoyed reading both Sam and Will. Sam is a smart girl, but more than that she is tough. She has been through a lot, and of course is dealing with a lot with her condition, so she is a strong girl. I also liked that Will was also a smart guy, he's definitely quick on his feet. And the two of them together are definitely cute.
As for the down side of the book, I can say the only thing I felt was lacking from the book was that I wish there was a bit more action in it. I hope that as the series progresses there will be more action in the books, but in this one I did wish there was a bit more. That being said, if you like YA books then I think you will enjoy reading this one.
