This book was simply amazing. Having read the trilogy, I can say that this is the best one in it by far. The author does a stellar job finishing up the story and weaving all the time streams together into one thrilling conclusion. All of your questions will be answered, and many of those questions will have suprising answers. Hautman does an amazing job of making Tucker, Lahlia, and Kosh feel like real people. Hautman also does a good job of making this time travel story feel not so far fetched that it could never happen in real life. I recommend this book to any teenagers that likes Sci-Fi, mystery, or action books.
