Screech! Some major interference is coming through on Walden's hearing aid.

But it's not the local radio station - it's a cry for help from the alien colonists called Arrok!

Their home has been blasted apart by an asteroid. Can Mr K and his students help? Will the same thing happen to Earth? And will the citizens of Arrok demand that Dani stay and serve as their leader?

There's never a dull moment in Mr Kazarian's spaceship . . . er, "library"! A science-fiction graphic adventure with lots of actual science - and lots of fun!
