Cover of Defender of the Flame Official Author Site of

Sylvia Louise Engdahl


Now available: my latest novel, Defender of the Flame. This is the first novel in the Rising Flame series. It follows the Hidden Flame series, consisting of Stewards of the Flame and Promise of the Flame, but it's a separate story set two hundred years later that doesn't depend on having read the preceding books. Some people like it better so I have split to two series to avoid labeling it Number 3, in the hope that new readers to whom the controversial medical issues in Stewards don't appeal will begin with Defender. Click on the cover for full information. It's not a Young Adult book and is not appropriate for middle-school readers (if you are wondering why, please read the Flame Series FAQ). However, it's of interest to adults and mature high school students who have enjoyed Enchantress from the Stars and The Far Side of Evil, as it deals with some of the same themes. A sequel, Herald of the Flame, will be published in late 2014. The Planet-Girded Suns updated edition


Recently issued: Updated paperback and ebook editions of my 1974 nonfiction book The Planet-Girded Suns: The History of Human Thought about Extrasolar Worlds, with a new Afterword, "Confronting the Universe in the Twenty-First Century." Click on the cover for full information.

Plus, a new print-on-demand edition of Children of the Star (all three novels of the trilogy in one volume), as all copies of the Meisha Merlin edition are gone. Also available: paperback and audiobook editions of This Star Shall Abide (known in the UK as Heritage of the Star), Book One of Children of the Star. Unlike books Two and Three, it can be enjoyed by readers as young as 12, so it is now available separately for those wanting a book for middle-school readers.

From the Reviews of My YA Novels

On Enchantress from the Stars: "Not just a novel for young adults but also one of the finest sf novels ever written--a classic of the genre. The only possible complaint one can make is that, after finishing it, you will likely find yourself disinclined for a while to pick up anything else in the genre for fear it will, as it were, taste of ashes. In sum, it is almost impossible to convey how good this book is. Please just read it." --John Grant, Infinityplus


On The Far Side of Evil: "Fiction doesn't have to be profound, just entertaining. But every once in a long while, a novel comes along that is both... [It] speak[s] to the very place of humanity in the universe, and what we need to do to attain and claim it. In an age in which terrorism has threatened our ways of life in unexpected ways, Engdahl's probing story, and the recommendation it contains, are especially relevant." --Paul Levinson, author of Unburning Alexandria


On Journey Between Worlds: "A beautifully-written, heartwarming, and scientifically plausible novel. What's more, it's quite a lot of fun... The sort of thing that's easy to devour in one sitting, and though short, it will leave you satiated afterward. On the other hand, now that I'm done with it, I want more." --John Joseph Adams, Orson Scott Card's Intergalactic Medicine Show,


On Children of the Star: "Once again, Engdahl creates a believable and thought-provoking piece of sf/fantasy that doesn't fall to the usual ray-guns-or-dragons cliches. The questions raised about freedom in this book kept making me pause in the middle of a page, thinking deeply about what was being shown in the story... For fans of originality/ intelligence: there's plenty." --E. A. Solinas, Amazon.com


From the Reviews of My Adult Novels

On Stewards of the Flame: "A thought provoking novel that may make you question the authority and direction of modern Western medical practices. I recommend it to anyone who enjoys reading genre fiction with some substance to it." --Anna Creech, Blogcritics


On Promise of the Flame: "It is not necessary to read the first [book] in order to be enthralled by the second... Engdahl's gift is to make her characters seem comfortable and familiar to the reader, even though their circumstances are not. Although clearly a work of science fiction, the ideas and futuristic possibilities are disturbingly real and will remain with the reader long after they've finished the book." --Peggy LaVake, IndieReader Staff Review


On Defender of the Flame: "This book reaches back to the brio and speculation of Engdahl's classic books of the Seventies... The reader will be taken on an exciting and suspenseful ride... With an admirable protagonist and many interesting and well-drawn characters major and minor, Defender is satisfying on multiple levels... I expected to like this book; I was startled that I loved it. A must read!" --Nicholas Birns, author of Understanding Anthony Powell


From the Reviews of The Planet-Girded Suns

"Engdahl has marshalled an impressive and fascinating selection of primary sources... [She] has shown how deep this vein of speculation runs ... and reminded us that our ancestors entertained a view of the universe that was larger and more imaginative than the history books lead us to believe. Challenging and original." --Kirkus Reviews
