The Last of the Thirteen is the fourth and final volume of John DeFilippis' epic fantasy series, "The Medallion of Mavinor." Picking up where The Crusade Against Darkness left off, it follows our heroes' plight as they aim to defeat Malgyron's forces and eradicate the darkness once and for all. While some go their separate ways to fulfill specific roles that have been assigned to them, others march together to wage an epic battle that could well determine the fate of the world. But as the conflict comes to a head, all of them realize one thing-they will need more than just courage and might to win the day. For the most lethal weapon they wield is neither sword nor shield, but rather the faith that resides deep in their hearts.
