By Jendia Gammon, writing as J. Dianne Dotson

An epic science fiction and fantasy tale with a rich array of characters and settings, Ephemeris: The Questrison Saga®: Book Two takes place before, during, and after Heliopause: The Questrison Saga®: Book One, and follows origins, convergences, and some familiar faces in The Questrison Saga. From Nebula and BSFA award finalist author Jendia Gammon, writing as J. Dianne Dotson.

Visions of doom. A growing evil. A new hero emerges as old alliances unravel.

Plucked from space and raised in a star-city of androids, impetuous Galla-Deia looks human but is not. Chosen to stop the dual threats of a galactic natural disaster and a malevolent alien entity, she must grow as a commander and gain the trust of both humans and non-humans alike. Unknown to her, the entity draws zealots to its cause, destabilizing interstellar order, and threatening all life in the galaxy.

Start the saga with Heliopause! Follow Ephemeris with Accretion and conclude with Luminiferous!

“Ephemeris is a great follow-up to Heliopause. Again there is a fast pace and interesting twists. And the world-building was first rate.”

– Jonathan Maberry, NY Times bestselling author of NecroTek and the Joe ledger thrillers


“…a rich, diverse galaxy with lots of distinct worlds and cultures, from flying castles to barren deserts to cyberpunk dystopias. It pays off a lot of the questions from the first book while still leaving a lot to mystery. Overall, great second book in the series, even better than the first. Highly recommended.”

– Alan K. Dell, author of The Augment Cycle and Flight of the Aurora


“Ephemeris is the second book in the Questrison Saga by J. Dianne Dotson, a sweeping fairytale of space travel and sorcery, eternal conflict between good and evil, and the paramount importance of friendship. Our understanding of the Questrison universe deepens, and we get to know the main characters like family. Mysterious devices, telepathy, sentient insects, clandestine organizations, and an ancient evil; our heroes have more than enough to handle.”

– Erik Martenson, author of The Last Navigator series


“This is the second J. Dianne Dotson book I’ve read and I loved it! Her writing style flows well and keeps you turning the page. I loved the addition of Galla (she’s my new favorite) and the backstory of Aeriod. Excited to see where the story will go next. 5/5 stars!”

– Dana Gricken, author of The Dark Queen and Modern Fairytale
