Book 50: Marooned in Realtime. The book that was suggested to me that Book 49 was the sequel to (and I missed a novella in-between them). I liked the concept, that there are these stasis bubbles you can be in where the world ages around you but you remain the same age. People bop around "through" time by letting it pass on outside the bubbles, strategically. This is more of a cop story than the last one which was more post-apocalyptic in some ways. Liked it in places, it dragged in others.
