The Legends of the Known Arc is a sweeping science fiction saga set in two worlds: our own contemporary reality, and a vast and enigmatic malfunctioning virtual cosmos. It’s an intricately plotted, award winning, cross-genre recipe of hard-SF and space opera (with flavors of LitRPG and cyberpunk), inspired by the works of authors like Adrian Tchaikovsky, Neal Stephenson and Dan Simmons.

The saga consists of a trilogy-in-progress plus standalone novels and short stories. The first trilogy volume, GRONE, was released in 2023 and the epic sequel ORUS is expected in 2024. A Known Arc companion novel, LONGSTAR, was released in February 2024. New short stories are regularly posted on this website, sign up for release updates below.
