Recursion

Blake Crouch

Helen is a Stanford neuroengineer who is working on a memory capture device. Her motivation is to try to develop a way to preserve the memories and life of her alzheimer laden mother. When funding dries up, she is approached by an angel investor who gives her everything she wants to develop her device. Barry is a NYC detective who is recently divorced, his marriage a shambles after the death of their daughter 11 years ago. Their stories are intertwined in a way that the fate of the world depends on. Turns out Helen's device is usable for time travel and the mechanism is built on a multiverse model where each time travel event spawns a new universe. This is an amazing story telling and system development. For the most part the time travel piece holds together and, while mind boggling, is fascinating and terrible. Really good sci-fi.
