From the author: "he King of Bayan acquires a halfbreed slave because he wants to learn more about the woodkin. But Ruari isn't all he seems, and he has his own reasons for wanting to learn about King Tarik."
From http://graculus.slashcity.net/recs6.html: "wanting to see the fabled king for himself, Ruari finds himself in over his head in more ways than one."
From fail-fandomanon.dreamwidth.org: "A young king takes a new bodyslave - but the bodyslave has his own secret agenda and motives. Powerplay, political intrigue, lost royalty, and cousincest."
