Six interconnected (barely) stories about human modification. It starts with simple human organ transplants and ends with non-modified (protos) living on reservations while the modified run things. The first four stories are okay, and I'd give this a so-so, but the last two longest chapters are excellent. The book takes a dark turn on how the line between modified and non would lead to slavery and segregation. 3💥💥💥 1/2 out of 5
