Leda Kills the Swan

Ancient Greek gods aren't exactly known for their strong sense of morality. For centuries Zeus has abused his position as king of the gods, kidnapping, transforming, and attacking mortal women-sometimes in the shape of a huge swan. But now he smells mutiny brewing, and paranoia is setting in. He's compiling a list of all the enemies he's made, including all the bastard sons he has neglected. He'll never suspect it's their mothers who are his greatest threat.
Leda is one such mother, out for revenge against her assailant-but there's one small problem: she's dead.
