Query: Unexpected and Intriguing

This shorter work by Robinson was totally unexpected. Like all of the Robinson's writing it is more character driven than plot driven as are his other works I've read - The Mars series and Years of Salt and Rice, and his climate change trilogy. This one was more enigmatic, but very provocative. It is the story of an amnesiac on an improbable world that allows the author to explore, but not answer, themes such as the nature of beauty, memory, relationships, the essence of being, and the perils or rewards of social interactions. It is as strange a story as I have ever read, but oddly satisfying, despite its abrupt ending. Read it.
