A speeding train, a blinding rainstorm, and the twisted remains of a car would haunt his life. His petty decision had cost the life of his prom date. That event was such a deep cut that he spent the next twenty years living like a hermit, working on a speculative theory to manipulate the relationship between matter and energy, and thus alter the reality of time. When his efforts paid off, and the technology to jump time was in his hands, it had seemed easy enough to jump back and fix that one fatal mistake. But nothing is ever that simple.
Normally I would give an exciting book like this, that I could barely put down so that I could eat, or go to bed, a five star rating. However, his detailed description of just how the processes of time travel were accomplished would cause me to stop, and ponder, "If this is really a work of fiction, why is it so convincing?" Highly recommend this book.
This was great fun. Complicated and fast paced, I could not always keep up with the characters when they were making quick jumps but the thread of the story held fast without requiring a lot of extra effort on my part.
