Recursion by Blake Crouch is an excellent, mind-bending read, much like his previous book, Dark Matter (reviewed here). My 14-year old and I both enjoyed both books, but I think I liked Dark Matter better. My same description of Dark Matter holds for this one. I am not sure I entirely understood all of it, but I enjoyed the ride, nonetheless. In this crazy story, Helena invents a chair intending to preserve the memories of people like her mother with Alzheimer’s. Instead, there are devastating results. This is a great end-of-summer-back-to-reality escape novel.
