Men in Black 2 – Esther M. Friesner

A novelization of the 2002 film starring Tommy Lee Jones and Will Smith.
When an unauthorized spacecraft lands smack-dab in the middle of New York’s Central Park, and is found abandoned with enough antimatter weapons to turn the island of Manhattan into a new Atlantis, it’s a job for Men in Black—the top-secret organization that monitors the activities of all extraterrestrials living on Earth. There’s a new ET in town, as beautiful as she is deadly.
