Time: Marked and Mended

Graff isn't quite human. His people move through the galaxy collecting memories and experiences, recording their lives and passing them on. Then, one day, he breaks: he discovers a chunk of his memory is missing. This should be impossible-he's never forgotten a moment in his life. Now, he has to learn to forget, and to remember, and this has consequences for all his people, his culture, and his whole world.
