Tash, Zak, and their uncle Hoole are on the run from evil Imperial scientist Borborygmus Gog. The only place to hide is on the Nespis 8, an abandoned space station.
There used to be a giant Jedi library on Nespis 8. According to Deevee, the library is still there, but it's cursed . . . and haunted by the ghost of a Jedi.
If they can find the library, maybe Tash and Zak can find a way to stop Gog. But something evil dwells on Nespis 98. And it's much scarier than a Jedi ghost.
