Half-blood means "different". Good or evil depends on the point of view.
The Genn, one of the Magical Races of the world, were banished from the Varian Empire almost sixty years ago, their last town destroyed twenty-five years ago. Half-bloods have a hard time fitting in, especially if they have no idea of what they have lost. So they find the most unlikely of friends - maybe even the Emperor himself.
An adventurous Silvery Earth novel of outsiders trying to fit in. Or not.
