There isn't a ton to like about this issue of Asimov's. The stories, besides the finale of Galaxy Blues, are just average. On the plus side, they're all science fiction and no fantasy. Yay.

• Serial: Galaxy Blues: The Great Beyond (Part 4 of 4), by Allen M. Steele - The conclusion of the story. It's a little disappointing, but overall I enjoyed Galaxy Blues.
• Novelette: The Ray Gun: A Love Story, by James Alan Gardner - An alien ray gun falls to Earth and manipulates the people and events around itself so that it gets dumped into the ocean, so it can come to rest next to the wreckage of the alien spaceship.
• Novelette: The Egg Man, by Mary Rosenblum - Zipakna traverses the Mexican desert in his metal dragon, bringing bioengineered vaccine eggs to the impoverished dirt farmers; he comes across a young boy who too closely resembles his missing ex-wife.
• From Babel's Fall'n Glory We Fled., by Michael Swanwick - Quivera is a diplomat to a race of inscrutable insectoid aliens, and when the alien city is destroyed, Quivera must risk his life to protect the racial memory of the aliens.
• Sex and Violence, by Nancy Kress - Reminds me of They're Made Out of Meat by Terry Bisson. Aliens are disgusted by humans, and in a temporal paradox, this causes the genesis of life on Earth.
• Inside The Box, by Edward M. Lerner - A physicist describing Schrodinger's cat is visited by an apparition claiming to be his grandson--who vanishes when the professor vows to never have children.
• The Last American, by John Kessel - A bizarre story of the future history of America, describing Michael Moore as a terrorist.
