It's easy to see why this is one of the classics of the genre. I don't often get into time travel narratives as much as I feel I ought to. Something about the mutability that has to be added to time to support that sort of plot mechanically tends to take away the weight of the story for me and drive down the stakes. Kindred is tight and personal, with the impact of twenty what-if-something-something-world-war-two books. Furthermore this book has the prose and relevance of something that could have been written yesterday, not thirty-six some-odd years ago.
