This special collection edition contains Stranger World, Stranger Realm, Stranger Tides, Stranger Desert, and Stranger Dream. The lines of imagination and reality have never been so blurred as in this amazing, yet sinister world of theme parks so creatively envisioned by Jack Castle

Welcome to Stranger World. In the future, people wanted more than just AI, they wanted to live their fantasies full time. Fast forward and the world has been taken over by full-immersion theme parks, but the attractions now run the show and humans are the entertainment. Available in print and ebook.


In a civilization built on fully-immersive theme parks, the attractions have taken over and humans are nearly extinct. The fearless Leftenant, a hologram perfect in every way -just ask her, is second in command of the HMAS Dauntless. In a final battle for humanity, her ship is shot down by Mad King Ludwig. She awakens a century later in a human body with no connection to her network or superior capacities. Now a wanted fugitive from the mad king, she is joined by Australian robot Outback Jack and six-legged scavenger Snafu. Together they must embark on a perilous journey across dangerous Stranger Worlds to reignite the flames of resistance or suffer a fate far worse than death, repurposement. “Oh, bollocks. What have I gotten myself into now?” Available for preorder. On sale August 2, 2024.

The Leftenant, a perfect hologram cruelly thrust into a human body, embarks on another perilous journey. Following the cryptic instructions of a mysterious device called the Thingamajig, she and robot adventure guide Outback Jack and French scavenger Snafu sail aboard the SoS Shipwreck to the floating island of Tournament World. There, in the shadow of Mad King Ludwig, chess-themed combatants from across the Stranger Worlds fight to the death in the annual gladiator games. Can the Leftenant solve the mystery and retrieve “the Rook" before the king’s Trenchcoats capture them?  Available for preorder. On sale November 2, 2024.
