Klatu, Lek, and Ploo head back to Groom Lake to fix their busted spaceship. But the spaceship is gone--it's been taken to Area 51. There's nothing for the aliens to do other than sneak in and search for it. Instead they find something they weren't looking for--the Great Ones! The mythic missing Looglians Org, Murkel, Shemp, and Kurth crashed at Roswell New Mexico in 1947, and have been in the deep freeze ever since. Can our three wacky alien kids rescue them? Dan Greenburg brings his trademark quirkiness and humor to the third book in his newest chapter book series.
