Input: Enjoyable ride through time from modern ages to the far far future of the universe. The action starts out slowly enough as the crew begin their journey but it builds speed with a nice deliberate pace. The scope and depth of the book accelerate inevitably and irresistibly along with the central characters themselves. One of my favorite aspects of the book is that it is paced very much like climbing a mountain. Just when you reach what appears to be the peak, you realize there is even more to come, beyond what you had previously imagined.The physical description of the effects of close-to-light travel is also quite enjoyable and is one of the features one would expect from Reynolds, as a former scientist and a noted hard-sci-fi writer. I tend to have a soft spot for stories that follow human civilization through a rapidly accelerating future history, in particular those that explore technological singularity or singularity-like events, and this one satisfies.
Output:
Positive
