The Harper Hall trilogy is a series of three science fiction novels by the American-Irish author Anne McCaffrey.

[4] Harper Hall's target was young adults[5] in contrast to the general audience for fantasy and science fiction.

Indeed, editor Jean E. Karl, who had established the children's and science fiction imprints at Atheneum Books,[6] hoped to attract more female readers to science fiction and solicited "a story for young women in a different part of Pern".

Dragondrums focuses on Piemur, a secondary character in Dragonsinger as a boy soprano, and one apprentice who made Menolly feel welcome.

The American Library Association in 1999 cited the two early Pern trilogies (Dragonriders and Harper Hall), along with The Ship Who Sang, when McCaffrey received the annual Margaret A. Edwards Award for her "lifetime contribution in writing for teens".
