It is the future.
Twenty years have passed since Eager's first adventures with the Bell family. Scientists are now banned from building robots that can think for themselves and feel emotion, like Eager. He and other robots have spent years in hiding. But Eager secretly visits the Bell family, and his headstrong nephew, a most unusual new robot named Jonquil, stows away on the visit. They arrive at the Bells just in time--for mysterious and dangerous things are happening to the family and their friends. Eager and Jonquil's special abilities could save the day.
The human world is totally new to Jonquil, who can't always tell fact from fiction. Excitable Jonquil is in his element. When he isn't in danger himself, he's causing havoc for everyone else. . . . From the Hardcover edition.
