Twelve-year-old Gabby is recruited by a secret agency to take care of extraterrestrial children.

Gabby Duran and the unsittables: The Association Linking Intergalatics and Earthlings (hereby known as A.L.I.E.N.) has a new member. After months of investigation, Gabby Duran, Associate 4118-25125A, has proven herself to be a babysitter extraordinaire. Her celebrity clients fly her around the country to care for their rambunctious little humans. Our spy, Associate 4118-23432B, otherwise known as Edwina, believes Gabby can be trusted with the truth: aliens are living among humans on Earth. And here at A.L.I.E.N we believe that even extraterrestrials need a babysitter now and then. No one was up to the task?until now. After accepting the top-secret position, Edwina has paired our new associate up with her first charge, a little girl from the planet Flarknartia. The timing for associate 4118-25125A is less than ideal. It's a school day on Planet Earth, Gabby's audition for the solo part in the band is tonight, and this tiny alien is a bit more than meets the eye. Can Gabby Duran, Associa
