When Derek Kunsken released The Quantum Magician in 2018, his plan for The Quantum Evolution series was that it would be a trilogy with a prequel novel. But as he reveals in the following email interview about that prequel novel, The House Of Styx (hardcover, Kindle, audiobook), the series will now include four novels, a collection of short stories, and a soon-to-be-released reprint of the novella that predated Magician, Pollen From A Future Harvest (paperback, Kindle, audiobook) , while Styx is now the first book in a prequel duology.
