Huntbrother — Michelle West

An old story: Girl who must marry for duty falls in love with boy who cannot fulfill that duty. The boy goes away to war, and war takes him; he never returns.
But this history is slightly different. The boy was given leave to return, in the casement of his god's flesh, and the girl, leave to spend one night with him. The night was glorious.
The morning was terrible.
And after?

This is the story of after, for Cynthia of Maubreche. It's a novella, set in the Kingdom of Breodanir, and takes place after the events of Hunter's Death.
