Pratchett's first children's novel was also his first published novel: "The Carpet People" in 1971, which Pratchett substantially rewrote and re-released in 1992. The next, "Truckers" (1988), was the first in "The Nome Trilogy" of novels for young readers (also known as "The Bromeliad Trilogy"), about small gnome-like creatures called "Nomes", and the trilogy continued in "Diggers" (1990) and "Wings" (1990). Subsequently, Pratchett wrote the "Johnny Maxwell" trilogy, about the adventures of a boy called Johnny Maxwell and his friends, comprising "Only You Can Save Mankind" (1992), "Johnny and the Dead" (1993) and "Johnny and the Bomb" (1996).
