The Bromeliad Trilogy by Terry Pratchett, epub

The Bromeliad Trilogy, aka The Nome Trilogy, contains Truckers (1989), Diggers (1990) and Wings (1990). Originally from Gramma6666's excellent torrent posted here but with typos and formatting errors fixed.

The trilogy tells the story of the Nomes, a race of tiny people from another world who now live hidden among humans. Through the books they struggle to survive in the world and, once they learn of their history from an artifact known as "The Thing", make plans to return home.

Diggers and Wings are to be read as contemporaneous sequels to Truckers, as each book follows different characters through (mostly) concurrent events. The central character throughout Truckers and Wings is Masklin, while in Diggers it is mainly Grimma.
