Interesting Concepts Yet Disjointed Storytelling. This is one of those books where there is nothing objectively wrong with it, and yet it also feels a bit disjointed. Separated into several parts, it could likely have been better separated into a trilogy, with the events of Parts 1 and 2 in one book, 3 and 4 in a second book, and 5 in a final book. Then you could expand each section out beyond what was presented in even these 400 pages (since you’d arguably need at least another couple hundred or so for a third book) and really make the effort to take a good tale into the stratosphere of being among the best in scifi. Overall the specific application of time travel here was one I hadn’t seen in any form since the early 2000s era Jet Li movie The One, and even here the specific direction Riddle applies is unique in my experience and intriguing overall. Ultimately this is a good tale and well told, it just seemed like it could have been better with a different editing approach. Very much recommended.
