Point Of No Return - The Evolved, #2

As a generation ship way past its pull date creaks and groans toward the nearest star system that might hold out a chance for survival, the scientifically literate Riggers turn to brain enhancements in a desperate attempt to discover new technologies. But a colony of evangelical Christians fear the approach of a "Point Of No Return" beyond which God's dominion ends, condemning their souls to eternal damnation.
Two teenagers, a Christian bee-keeper and a budding physicist, strike up a chance friendship that gradually draws them closer together as their worlds turn mad. Now the Christians demand the ship turn around. And if the Riggers refuse, the evangelicals would rather die on this side of the line - even if they must take the whole habitat with them. Leaving our star-crossed lovers reaching across an ever-widening gap as both sides escalate toward a final solution.
