sequel to In War Times, this one covers the children and grandchildren of Sam and Bette Dance. by now it's 1991, at least in Timestream 2. the third generation is young and precocious, and the enemy action less formidable, but the proliferating timelines and mutating nanotech devices of Eliani Hadntz make the worlds less stable to travel, particularly in the vicinity of the Dance family home. but Eliani's grand utopian plan involving empathy and education appears to be working. in some ways, it's about the elasticity of memory, how fluid it is when confronted with competing quantum histories, and how much family and communications matter in the distribution of space and time we navigate. altogether, the author doesn't devote as much time and glorious detail to the period as she does in the previous book set in 1945-1963, but it's lovely to get caught up on the Dance family and their interesting problems with living inside the lab experiment of creating a quantum world.
