Wings - Terry Pratchett

When you're four inches high in a world full of giant people, things never go very well for long. After running into trouble at the quarry, the nomes want to go home. The problem is, `home' is somewhere up in the stars, in some sort of Ship. Masklin must find a way to get to the `launch' of a `communications satellite' (whatever that is). And so begins an incredible journey, filled with peril, planes, honking geese . . . and a walking sandwich. The fantastically funny third book of the nomes, from the author of the bestselling Discworld series.
