How I Proposed to My Wife: An Alien Sex Story by John Scalzi
My rating: 5 of 5 stars
That was an unexpected short story. For one thing I went into it thinking it was the story of how Scalzi proposed. But once it was clear it was fiction, it still took me by surprise and the ending was unexpected. Scalzi continues to be my favorite source for funny (non-slapstick) science fiction. This story made the collection it came from worth getting.
