New $2.99 ebook edition of Journey Between Worlds


This novel is catregorized as science fiction because the story takes place on Mars, but it's not about technology or exotic adventure. It's mainly a story about human aspirations and human love. It has had two past hardcover editions and a paperback issued by major publishers, yet despite good reviews it has never reached the readers for whom it was intended. It was marketed exclusively as science fiction rather than romance, although avid science fiction fans aren't likely to sympathize with a heroine who doesn't want to go to Mars. It's enjoyed most by romance readers who may or may not be in favor of space travel, and who wonder whether in a changing world, there's hope for their descendants to find happiness. Space enthusiasts interested in Martian colonies also like the book, and they especially like recommending it to friends who don't see why anybody would want to live on Mars.

Flame Series now available in Kindle Unlimited


My two Flame series -- The Hidden Flame and the RIsing Flame, both the individual books and the "box set" editions -- can now be accessed by subscribers to Kindle Unlimited. (This new program allows borrowing up to 10 Kindle books at a time from Amazon.com for a fee of $9.99 per month. The author is paid according to the number of pages read.) With thousands of science fiction novels to read free in Kindle Unlimited, I feel it's unlikely that members will buy a book by an author with whom they're not already familiar. For my adult novels to get new readers, it's essential that they be included.

The downside is that while enrolled in Kindle Unlimited a book cannot be for sale anywhere except at Amazon.com, not even the author's own website, and copies cannot be given away. (This applies only to digital editions; paper editions can still be sold elsewhere, and I still offer signed copies.) I've therefore had to withdraw the ebooks of the Flame series -- but not my other books -- from all other retailers. You don't need a Kindle to read Kindle books; there are free apps for reading them on computers, smartphones, and most other devices. And of course, you don't have to subscribe to Kindle Unlimited, and whether you do or not, you can buy the Kindle books you want to keep. More information can be found here.

New covers for Stewards of the Flame, Promise of the Flame, and the Children of the Star trilogy


The books in the Hidden Flame series were recently given new covers to match the design of those in the Rising Flame series, and the cover of Children of the Star was changed. Those of the separate books in the Children of the Star trilogy were made more colorful when seen in a small size, but they did not prove very successful and have now been changed again, with large lettering that will stand out. (Also, the lettering has been enlarged on the covers of some of my other books' ebook editions, but not their paperback editions.) The interiors of the books have not changed.

Special Sale! SIgned copies of paperbacks with the old covers can be obained from me at my cost (including cost of postage) as long as they last. The purchase form on the book description brings up these discounted prices -- if you want the current covers, add $5.00 in the "shipping" box.

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

On Herald of the Flame: "A futuristic ride that has many parallels in today's society. This is a 'thinking man's' science fiction book - the type we need more of today!" --The Feathered Quill

On the Rising Flame series: "These novels are not so much genre 'Romance' or even just 'Science Fiction' as they are Literature. These are novels about life." --Jacqueline Lichtenberg, Alien Romances: Reviews 14


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
