'The Night the Cylons Landed' (Part 1) by Glen A. Larson

When a specially-modified Cylon ship is shot down by Colonial Vipers, the vessel crash-lands near New York City on Earth. Two of the crew survive: a Cylon warrior and a new type of Cylon, a humanoid android named Andromus. Lieutenant Troy and Lieutenant Dillon are sent to track down the enemy before they can come into contact with humans, but they are too late: the two Cylons have managed to hitch a ride with a young couple on their way to a Halloween party…
