About the Acorna series

A trio of asteroid miners find an abandoned escape pod carrying an infant who is unmistakably, impossibly, part unicorn — a silver-maned, horned girl whose horn can purify poison and heal wounds, and who grows at an accelerated rate into a young woman determined to find out where her people came from and why they were destroyed. Anne McCaffrey co-created Acorna with Margaret Ball for the 1997 debut, then continued the series for eight more books with Elizabeth Ann Scarborough after Ball departed, building out a science-fantasy universe where genetically engineered 'Linyaari' unicorn-people, ruthless intergalactic slavers, and asteroid-belt mining corporations collide.

As the series grows, it widens from a fairy-tale premise — a unicorn girl raised by kindly miners — into interstellar politics: Acorna reunites with her own species, confronts the predatory Khleevi who nearly exterminated the Linyaari, and eventually starts a family of her own, whose adventures continue the story into the Acorna's Children spin-off trilogy. McCaffrey and her co-authors keep the emotional core consistent even as the scope escalates: found family, the ache of displacement, and a horn that heals standing in for a character who would rather fix the galaxy's cruelty than merely survive it.

Who co-wrote the Acorna series with Anne McCaffrey?

Margaret Ball co-wrote the first two books (1997-1998). Elizabeth Ann Scarborough took over as co-author from Acorna's People (1999) onward and wrote the rest of the series, including the Acorna's Children trilogy, with McCaffrey.

Is the Acorna series connected to the Dragonriders of Pern?

No, it's an entirely separate universe with its own species, technology and setting.
