"Beware the unanswered riddle."
I just started Heir of Sea and Fire, book #2 of Patricia A. McKillip's Riddle-Master Trilogy.
Who won the riddle-game with Peven of Aum? Morgon of Hed, and thus did he win the right to marry Raederle, the second most beautiful woman in the three portions of An. But wining that riddle-game began another, and now Raederle must find the farmer-prince as deadly riddles gather like blood-crazed crows in and for a battle barely understood.
