Sylvia Engdahl

Sylvia Louise Engdahl (born November 24, 1933) is an American writer, known best for science fiction. Her debut novel Enchantress from the Stars, published by Atheneum Books in 1970, was the 1971 Newbery Honor Book (see Newbery Medal), was a Geffen Award finalist in 2008, Best Translated YA Book, and she won the Phoenix Award for that work twenty years later.

Biography
Engdahl was born in Los Angeles, California. The Internet Speculative Fiction Database lists 11 books by Engdahl that were published from 1970 to 1981, including two anthologies she edited and three nonfiction books. Her first six books were all published by Atheneum Books. From 1985 to 1995 she taught graduate courses for Connected Education, a pioneer in online education. She lives in Oregon.

In August 2007, Engdahl published a new adult science fiction/visionary fiction novel, Stewards of the Flame: The Hidden Flame Book 1, which she followed with Promise of the Flame: The Hidden Flame Book 2 (September 2009). She followed this duopoly with a trilogy that can be read separately, Defender of the Flame: The Rising Flame Book 1 (April 2013), Herald of the Flame: The Rising Flame Book 2 (October 2014), and her most recent novel, Envoy of the Flame: The Rising Flame Book 3 (June 2021).

Selected works
Among 73 Library of Congress Online Catalog records of books created by Engdahl through 2014 (which may include multiple editions of some), all but the first 16 are nonfiction anthologies she edited while working as a freelance editor.

Science fiction novels
Engdahl wrote six science fiction novels published from 1970 to 1981 by Atheneum, all of which have been republished in the 21st century. Her latest novels, a duology published in 2007 and 2009 and a trilogy published in 2013, 2014, and 2021 respectively, are adult science fiction, not YA.
