Duologies' omnibus editions now available in paperback

The omnibus editions of my two Flame duologies, The Hidden Flame and The RIsing Flame, are now available in paperback as well as in Kindle format. The paperbacks have been issued primarily to make these novels available in the Baker & Taylor catalog used by libraries, since the individual novels have ISBNs that for technical reasons are not eligible for inclusion -- libraries cannot easily order books that aren't in that catalog. Another benefit is that you can save a total of $10 over the individual novels' retail list prices, or $8 off my regular discounted prices, by buying the omnibus editions instead of the separate ones. Print-on-demand books are expensive and I try to keep my prices as low as possible, so I'm happy to offer an opportunity to obtain them for less than in the past. However, the omnibus editions have smaller print than the separate ones.

Some of my books can be read via Kindle Unlimited

My two Flame duologies -- The Hidden Flame and the RIsing Flame, both the individual books and the "box set" (omnibus) editions -- are now available in Kindle Unlimited. (This 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 subscribers 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 novels -- 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. Whether you do or not, you can buy the Kindle books you want to keep. More information about ebook formats and availability can be found here.

My nonfiction book The Planet-Girded Suns: The History of Human Thought About Extrasolar Worlds is also available to borrow through Kindle Unlimited. Because on their KU promotion days books are shown at Amazon in lists where they are more easily found than by browsing the entire catalog, this means it is seen by readers who would otherwise never hear of it. During its recent promotion, it reached #1 in the Top 100 Free Best Sellers lists for both the "Astromomy & Space Sciences" and "Science History & Philosophy" categories.

New ebook edition of Journey Between Worlds


This novel is categorized 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.

More new covers: Defender of the Flame and This Star Shall Abide


The books in the Hidden Flame duology, Children of the Star, and the separate books in the Children of the Star trilogy were all given new covers recently, and the lettering on the ebook editions of both Flame duologies (but not their paperback editions) was enlarged to make it stand out more when seen in a small size. Now the cover of Defender of the Flame has been improved, as I suddenly saw a way to modify it that I wish I'd thought of in the first place. I'm sorry that people who've bought it in the past have the old one! Both the ebook and the paperback covers are shown here. In addition, the UK title of This Star Shall Abide has been added to its cover and book catalog title, which I also wish I'd done long ago. UK readers looking for Heritage of the Star haven't always found it, and I belatedly realized that it will come up in searches if included as a subtitle.


Free ebooks to owners of paper editions: If you ever bought a new hardcover or paperback copy of one of my books (except Enchantress from the Stars) at Amazon.com you are entitled a free copy of its Kindle edition through the Matchbook program. The Kindle price will automatically show as zero on your account. If you bought a copy directly from me and would like an ebook copy, let me know and I will send you one.
