The Mapmakers

"If there is a war," said Lily slowly, "Which side do you think you'd find yourself on?" "Whichever side you're on, obviously." It's 1975, and Whoever-He-Is has turned his eyes towards Hogwarts. Lily Evans, James Potter, and Severus Snape are about to be tested in ways they cannot imagine. A canon-compliant account of the First Wizarding War and the teenagers who fought in it.
