Worth reading but I wasn’t up on all the literary references as much as you need to be. The quality of the writing was obvious and superb, but, oddly for a novella, I felt it a little too long. I wanted the story to move on from the love letter correspondence between Red and Blue one or two letters earlier. The immersion that was achieved for the diverse locations with such brief descriptions was my highlight. There’s a mystery character appearing at the end of each letter, and although readers (esp. any fantasy/SF reader) would spot who that is, when we actually meet them, for the end game, I got more into the romance of it.
