author
b. 1880
Best known for the 1910 novel Ragna, this early 20th-century writer created a coming-of-age story that carries readers from a rugged Scandinavian childhood to a more polished world abroad. Her work has endured through library collections and Project Gutenberg, where modern readers can still discover it easily.

by Anna Miller Costantini
Very little biographical information about this author could be confirmed from readily available reliable sources during this search. What is clear is that Anna Miller Costantini is identified in library and public-domain records as an author born in 1880.
Her best-known work appears to be Ragna, published in 1910 by Sturgis & Walton Company. Public-domain and library listings describe it as an early 20th-century novel, and modern catalog summaries present it as a coming-of-age story following a spirited young heroine from Norway into a wider European world.
Because so little verified personal history was available, her surviving reputation today rests mainly on the novel itself and its continued circulation through archives and Project Gutenberg. That gives her a small but lasting place among rediscovered authors whose work has remained accessible to new generations of readers.
