A parallel-universe hard science fiction thriller in which the drive that brings a crew home may have broken reality itself. Mind-bending space suspense of quantum travel, wrong Earths and one-way mistakes.
They made it home. But it isn't their Earth anymore.
After a harrowing mission to the Trappist-1 system, Mark Noble and his enhanced crew return using the new spolding drive, a prototype engine that folds space to enable near-instant travel between stars. But something's wrong. The satellites are missing. The space station is gone. And the world below looks. Untouched.
As the truth sinks in, one terrifying possibility emerges: the spolding drive didn't just bring them home. It brought them somewhere else. Now stranded in a parallel reality, with no way to call for help, the crew must retrace their path across the stars, hoping to undo what they've done before they're lost forever.
Publisher's note: Replica Paradox was previously published as The Spolding Conundrum.
Perfect for readers of Blake Crouch, Arthur C. Clarke and Peter Cawdron, parallel-world sci-fi thrillers packed with quantum travel, alternate Earths, and crews racing to undo the impossible.
Praise for the Mark Noble: Edge of the Void Series:
★★★★★ Reads like old masters--classic hard sci-fi with emotional depth.
★★★★★ Solid science, real people, strange situations, clever solutions, and unexpected twists. I will read more of this series.
★★★★★ Most innovative sci-fi author I've read since the 50's old masters of sci-fi!
★★★★★ Reminded me of Doctor to the Stars because of the infection.
★★★★★ Believable characters and details, coupled with only modest 'suspensions of disbelief'... makes me eager for the unfolding story.
★★★★★ Fast and easy reading. Kind of like an Alien movie.
★★★★★ Good page turner. Fun and exciting without resorting to needless violence.
★★★★★ I haven't been so excited about sci-fi since I first read Heinlein. This is better!
★★★★★ Classic hard sci-fi without fluff. Reminded me of Clarke, Asimov, Bradbury.
★★★★★ Tony writes what I call real science fiction, like the old masters.
★★★★★ Exciting and nerve-wracking... it had me enthralled throughout the entire book.
★★★★★ A fresh approach to aliens--finally something different than the usual invasion trope.
