Windhaven

Among the scattered islands that make up the water world of Windhaven, no one holds more prestige than the silver-winged flyers, romantic figures who cross treacherous oceans, braving shifting winds and sudden storms, to bring news, gossip, songs and stories to a waiting populace. Maris of Amberly, a fisherman's daughter, wants nothing more than to soar on the currents high above Windhaven. So she challenges tradition, demanding that flyers be chosen by merit rather than inheritance.
But even after winning that bitter battle, Maris finds that her troubles are only beginning. Now a revolution threatens to destroy the world she fought so hard to join - and force her to make the ultimate sacrifice... This early collaborative novel from George R. R. Martin and Lisa Tuttle is a masterclass of fantasy and storytelling.
