Guilty by P G Saunders

How far would you go to prove your innocence, if you were falsely accused of a crime you did not commit?


When an act of revenge ignites a chain reaction across the Jovian system, a wrongly accused couple set out to clear their names, and set in course a revolution that benefits everyone.

Far from Earth, all is calm on Zephyria Station, the diplomatic and administrative hub of the Jupiter system. Until, that is, an engineered crisis occurring on Ganymede, turns everything on its head. An experimental bioweapon, Xylocene-9, is released by mistake on Catania Base, unleashing a wave of chaos rippling across the Jovian Moons. What began as a simple accident becomes an interplanetary crisis, as governments lie, alliances fracture, and truth itself turns toxic.

At the heart of it all stands Dr. Lucia Monteiro, a scientist framed for triggering the outbreak and her partner, humble engineer Frankie Williams. Hunted by her former mentor and lover, Eric Duprey, whose cold ambition eclipses every moral boundary, Lucia and Frankie are forced to flee across the moons of Jupiter with only their intellect, courage, and a handful of unlikely allies to assist them.

Together, they uncover the real agenda behind the contagion, one woven through the politics of Zephyria, the laboratories of Armstrong, and the hidden networks of Io. The outbreak was no accident, and it was the opening move of a system-wide power play that will decide who controls humanity’s future beyond Earth's reach.

As the virus spreads and panic consumes the colonies, Lucia and Frankie become fugitives, moving from frozen moons to burning skies, from their high powered jobs on Zephyria to the dangerous caverns on Callisto. Every step forward peels back another layer of deception, until the only way to survive is to confront the architect of the disaster himself.

“Then we prove the truth,” Lucia swears, as Jupiter’s storms churn above them.

From the first laboratory breach to the tense confrontation at the Europa Transit Hub, Guilty by P G Saunders fuses the tension of a high-stakes thriller, with the humanity of a survival drama.

The novel moves between heart-stopping action and quiet moments of loyalty, fear, and love, showing that even in the darkest vacuum of space, the human spirit can still burn brighter than any star.
Featuring cinematic realism, layered dialogue, and emotionally driven storytelling, Guilty

Authentic science-fiction world-building grounded in plausible technology and psychology.

Complex, interlocking characters whose choices carry moral weight.

A viral-outbreak mystery that becomes a battle for truth amid political corruption.

A sweeping narrative that travels from Catania’s laboratories to Zephyria’s command decks and the perilous moons beyond.


If you love the intensity of Michael Crichton, the moral complexity of The Expanse, and the emotional reach of Station Eleven, you’ll be at home here.

In a system built on lies, one woman’s integrity could rewrite everything. But survival comes at a price, and on Jupiter’s moons, even the air that you breathe has an agenda.

Guilty by P G Saunders is more than a sci-fi thriller.
