THROUGH A FOREST OF STARS is the first book in Jeffrey’s Space Unbound series, setting the hard sci-fi foundation for the next three sequels. SUN WOLF, Book 2, and THE LIGHT WITHIN DARKNESS, Book 3, continue the hard sci-fi adventure. Book 4 in the series, QARSOON, was released on January 27, 2026, continuing the story of Captain Aiden Macallan and the crew of the Sun Wolf.

The books in the series have received praise from Publishers Weekly, Kirkus, have been chosen as EDITOR'S PICK by Publishers Weekly BookLife, and have received STARRED REVIEWs from BlueInk Reviews. Jeffrey's brand of hard sci-fi storytelling has been compared to the works of Author C. Clarke and James S.A. Corey’s Expanse series.
