When Gabby Duran moves to quiet Havensburg with her successful mom and overachieving little sister, she's recruited by her school principal for a special babysitting gig. The fearless and unapologetically bold new girl in town soon discovers her young charges aren't your standard unruly kids. They are very important extra-terrestrial children hiding on Earth with their families, and it's her job to protect them and their secret identities, and prove she's the best babysitter in the galaxy!

CASE FILE: THE FINAL (?) UNSITTABLES SUMMARY: With the entire Unsittables program in jeopardy of termination, Gabby Duran, Associate 4118-25125A has been tasked with caring for three young charges on the afternoon of a highly important Planetary Treaty Association (P.T.A.) meeting-one that could change the fate of the entire galaxy. While Gabby has proven in the past to be resourceful in a crisis, the members of A.L.I.E.N. currently have serious doubts about whether she has what it takes to protect the lives, and the identities of aliens here on earth. But we've decided to give her one last chance to prove herself. Of course, it won't be easy. Her three new clients hail from three different alien planets and each have special powers that require a deep well of patience on the part of their caretaker. We also have recently received word that one of her charges, a young girl by the name of Sharli, has become the target of certain unsavory intergalactic elements who might wish to do her harm. Will Gabby manage to keep the girl safe (and on-planet) until her mother returns from her P.T.A. meeting? Will any of us live to tell the tale? This fast-paced, planet-hopping, laugh-inducing novel perfectly wraps up the Gabby Duran and the Unsittables book series while catapulting readers into the action of the new Disney Channel Original Series of the same title, now airing on Disney Channel!

Discover the hilarious adventures of a plucky babysitter that inspired the Disney Channel original series! Gabby Duran and the Unsittables Case File: The First Unsittable Summary: 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, Associate 4118-25125A, First Sitter to the Unsittables, keep her otherworldly charge safe in the unpredictable halls of middle-school and keep A.L.I.E.N hidden? Gabby Duran: Troll Control Case File: The Second Unsittable Summary: Here at A.L.I.E.N. we believe in strengthening the bonds between humans and intergalactics so that one day all beings can live together on Earth in harmony. That day has not come. But our Associates are working hard to achieve this goal, including Gabby Duran, Associate 4118-25125A, Sitter to the Unsittables. Upon successfully completing her first mission, we have assigned Gabby a more . . . puzzling charge. The relationship between trolls and humans has always been rife with tension, and the troll family Gabby is assigned to is especially prickly. But Gabby is not fazed. Our footage shows Associate 4118-25125A playing, laughing, and snacking with Trymmy, the little troll boy, who seems to be thoroughly enjoying himself. Our liason, Edwina, informed Gabby that trolls love nothing more than a riddle-and stealing items from unsuspecting humans to add to their trove-but Gabby's certain that all this young troll wants is to have fun. However, it might not be as simple as she thinks. After all, there's a reason this particular alien offspring has been labeled "Unsittable."

This all new Gabby story bridges the gap between the action of the trilogy and the Disney Channel Original Series.
