ABOUT G. S. JENNSEN
G. S. Jennsen lives somewhere in the U.S., in a locale that may or may not be where she lived the last time she published a book (she’s a gypsy at heart), with her husband and one or more dogs. She has become an internationally bestselling author since her first novel, Starshine, was published in 2014. She has chosen to continue writing under an independent publishing model to ensure the integrity of her stories and her ability to execute on the vision she has for their telling.
While she has been a lawyer, a software engineer and an editor, she’s found the life of a full-time author preferable by several orders of magnitude. When she isn’t writing, she’s gaming or working out or getting lost in the mountains that loom large outside the windows in her home. Or she’s dealing with a flooded basement, or standing in a line at Walmart and wondering who all these people are (because she’s probably new in town). Or sitting on her back porch with a glass of wine, looking up at the stars, trying to figure out what could be up there.

** JUNE 12, 2026 ** in ebook, paperback and hardback (audio on the way).
For 23 books, the Amaranthe saga has swept you across multiverses: from Alex's dimension-defying explorations and Caleb’s world-saving heroics, to Nika's kyoseil-fueled rebellions and Miriam's strategic machinations. You've witnessed sentient planets awaken, AI-human symbioses redefine life, and unlikely alliances overcome impossible odds. But now an ancient enemy, the Dzhvar, have returned, and the universe’s days are numbered - unless Alex can find a way to save it. Her quest to find the key that unlocks everything will take her farther than any mind was ever meant to venture—and beyond.
You can pre-order the ebook from your favorite retailer today, and it will be waiting for you in your ereader / app on the 26th. You can also preorder a signed paperback or the audiobook directly from me. And did I mention I love the cover? Because I LOVE the cover.

Kobo Plus is featuring both Starshine and Exin Ex Machina this month, as part of a big SFF promotion. What’s Kobo Plus, you ask? Well, it’s a sort of “Netflix for books.” Much like Kindle Unlimited (KU), except it’s cheaper for readers ($7.99 vs $11.99 in the US), it includes audiobooks as well as ebooks, it’s available in a bunch of countries, and it’s fairer to authors. How? Well, in order for a book to be in KU, Amazon requires it to be published exclusively on Amazon. Kobo Plus, however, has no such requirement. This means all my books and audiobooks are available in Kobo Plus - and so are offerings from a ton of talented authors.
Best of all? The first month’s free, so you can try it out and see if you like it.
Kobo has a great free reading app you can install on your phone, tablet or computer, just like Kindle (they also make extremely high-quality ereader devices, if you decide you’re all in on Kobo). So check out these featured scifi and fantasy ebooks and audiobooks on Kobo Plus today (just a small sampling of the many titles available). Click on a book that catches your fancy, and you’ll be prompted to start your free trial. Enjoy!
