Android’s Dream (2006)  John Scalzi

Do Android’s Dream of Electric Sleep? – Phillip k. Dick

Scalzi is channeling Heinlein in this fun book that includes aliens (multiple), artificial intelligence, genetic experimentation, religious cults, and corrupt government officials (what’s new?). 

Harry Creek is a war hero who now works delivering bad news to unruly aliens.  He is now asked to find a special sheep (Android’s Dream) that is necessary for an alien ceremony.  If he cannot find one the aliens will wage war on the Earth with their superior battleships.  Fortunately, the sheep DNA is found in the junk DNA in a pet shop owner.  Watch Harry and his best friend Brian (now an AI) maneuver to a possible solution to keep sheep-girl (Robin Baker) alive and protect the human race.
