This is the first fantasy/ world/ book/ creation!

Written when Terry Pratchett was 17 years old it took 3 years to get published in 1971.
Imagining there's a whole world going on in your carpet under your feet, does show an incredible imagination.
2021 is the 50 th. Anniversary and a reprint is now available. It's a hilarious fantasy, co written by Terry Pratchett, aged 17 and master storyteller, Terry Pratchett age 43! See extra.
Not his best work but a very good start!
