Norby's Other Secret — Isaac Asimov

Scheming scientists want to find the secrets behind Norby's antigravity abilities -- but they have to dismantle him to do it! The mixed-up robot and young space cadet Jeff Wells go on the run to Jamya, a planet inhabited by hungry dragons and angry robots. Will the futuristic friends survive, and can Norby's newly discovered telepathy and time-travel powers save the day?
The second book of The Norby Chronicles, this novel was written by Janet Asimov and her husband, Isaac Asimov -- the author of I, Robot and many other robot stories. It's a great way to introduce young readers to the thrills of science fiction.
