Elevator to Nowhere

Publisher blurb Uncle Darius is an inventor. Right now he's testing out his transuniversal Transvator. It looks like an elevator- but it takes passengers to other universes! Uncle Darius says he'll prove it by bringing back a special souvenier- a shrunken head. But when Uncle Darius returns- something is wrong. How wrong? He wants to shrink your head! And your only means of escape is battling his headhunter on earth- or battling the unknown in the other universe. Hurry-the doors are closing!
