The quest for identity in Aria of the Sea is an integral part of Robin McKinley's The Blue Sword and The Hero and the Crown, and of Lloyd Alexander's Prydain Chronicles. The young women, Harry (born Angharad) and Aerin in McKinley's two books struggle to make a place for themselves as strong women in a male-dominated culture. In Prydain, a young orphan named Taran chases after his master's runaway prophetic pig and discovers hidden depths in himself that he never realized were there as he makes a stand against evil. Patricia McKillip's The Changeling Sea also features a maritime theme and a young woman who accidentally hexes the ocean queen and frees a prince. Monica Furlong's Wise Child and its sequel Juniper contain elements of fantasy.
