A vast chasm divides two species. But there is a bridge - and the bridge is a man.
The Tolek and humanity were never meant to meet. Two civilizations built on opposite logic, facing the same impossible claim: Earth. To humanity, it is home. To the Tolek, it is the only acceptable solution. They fear each other, misread each other, and cannot see the universe the same way.
Between them stands Alexis Dren - the only mind that can follow Tolek logic far enough to challenge it, and human enough to understand what failure will cost.
Earth and Mars have fought the Tolek to the edge of a decision that cannot be unmade. Now the war moves from the battlefield to the negotiating table, where a single misread intention could end one species - or both. But not everyone at that table wants peace, and the most dangerous threats to humanity's survival may not be alien at all.
Can Alexis Dren strike a bargain that leaves neither species extinct? And if he does - what is its price?
Satan's Bargain is the taut, intelligent conclusion to Operation Clean Slate, a hard science fiction series grounded in real physics, real engineering, and the uncomfortable logic of how civilizations actually behave under existential pressure.
