This is an intriguing tale of time travel by Cristin Terrill. It deals with the consequences of the choices we make and the way that some of those choices become turning points in our destiny. Em and Finn escape from their cells and travel back in time to stop their friend James from completing his research into time travel. Em finds a note she has left that shows they have tried this many times before in different ways and always failed. The narrative switches back and forth from her point of view to that of young Marina, who exists in that earlier time. Slowly we begin to see how things have unfolded and what results from each of those choices. There is also a very cool description of space-time comparing it to the surface of a trampoline. Some events barely make a ripple, some are important or strong enough to cause it to bulge out of shape, and some things hit with enough force to punch right through it.
So many YA novels today seem to deal with a love triangle of some sort, but this has a different feel to it - even though Em loves James and Finn. For older readers, the regrets that Em and Finn voice about their earlier choices will ring true; we all have things in our past that we regret or cause us to wonder "what if." For younger readers, this is a glimpse into what that regret can feel like, even though you probably haven't experienced it yet.
If you enjoy time travel adventures like the Infinity Ring series, or movies like "Clockstoppers," then you will probably enjoy this book. I would recommend it for middle or high school ages due to some of the language used. I should warn you, it is addictive. I read it through in one sitting because I just had to know how it ended.
I read an e-book provided by the publisher through NetGalley, but it went on sale in stores on September 3, 2013.
The author's website features prequel webisodes (a video series that sets the scene for the book), as well as information about the author and her books. The publisher also has a teaser video.
