Moon Trap — Frank Carey

Exploring ancient laboratories on Earth's moon is never a good idea but throw in a group of extraterrestrial tomb robbers and one should expect all kinds of bad.

While attending a UFO Conference in Las Vegas, Lee and Clare are kidnapped by a group of extraterrestrials bent on using Clare's computer skills to gain access to an abandoned lab on Earth's moon. Once inside, Lee, Clare, and the kidnappers find themselves in a trap that none of them may escape.

Moon Trap is the second book of the Prehistory of the League of Planetary Systems where feeding the livestock takes on a whole new meaning.
