Britta Boyle wants to throw a festive Ceili to impress her neighbors so she does a little wheeling and dealing with the powerful faerie Fethowyn. She meets the wily little fellow in the bog one late November Eve and they seal their pact with a handshake that leaves Britta with an indelible mark and a stern warning- don't cross the fae or dire consequences will be felt.

Britta's poor husband, Seamus, must find a way to save his impetuous wife from the Faerie Realm and enlists the aid of the local barkeep who learned a secret from Fethowyn himself that will send the fae packing!
