Killgrace and the Faithless

Why would a species abandon science and shun reason? Why is there such a schism in the culture they have just discovered? And why did Susan have to discover it by being arrested and sentenced to death? Sometimes a scientist's life can be more interesting than it really needs to be.

A science-fiction novella.

The Killgrace series: Two scientists, one purely alien, one advanced humanoid, trapped on Earth in the past. Their only way home is the long way, living it straight without disturbing events too much, but the world they came from was at war - and they weren't on the same side.
