I'm surprised nobody mentioned one of my favorite fantasies, Lois McMaster Bujold's The Curse of Chalion, only 99 cents at
Amazon,
Kobo, and elsewhere. I think the price goes back up to regular price at Kobo in 15 minutes, though. It's set in the same world as the Penric novellas, and The Hallowed Hunt, and The Paladin of Souls, but the 3 novels are totally independent and can be read in any order.
