Bitel retells little-known, anonymous tales from Ireland, written a thousand years ago or more, about human and supernatural lovers who cross the boundaries between our world and the Otherworld (síd). Set in a lost time of heroes, demi-gods, warrior queens, and otherfolk of the Irish Otherworld (áes síde), these stories inspired some of the earliest fairy tales of France and England—but they are sexier, funnier, and bloodier than better-known medieval myths and romances.
