This book was exciting - with all the jumps between space and time, the mystery, the action, the plot twists. I really enjoyed it. It had a great beginning that really just sucked me in to the book and once I got started, I couldn't put it down. The characters are great, but, though interesting, they were not as drawn out as I would have liked, but still well done - I can't wait to read more about them in future books. The science of it all is well written and interesting. Definitely a good fun read. :)
Note: I received a copy of this book in exchange for my honest review.
