At last, the dreaded night of the Red Moon is dawning for Prince Cyrus and his misfit band of adventurers. If they don't reach the stronghold of the Everblood vampires by nightfall, the fiends will dine on Trinity Toccatta, the princess Cyrus swore to protect, and remain their youthful, demonic selves for another 666 years. What stands in the way for Cyrus is an icy tundra, a village of insane cultists and army of demons sent from the Dark Realm itself. Will he and his friends be able to brave these treacherous dangers and make it to the Forbidden Fortress in time?

And even if they do, will they be able to defeat four of the most powerful Everbloods in all of the Dark Realm?

Find out in this exciting last installment of The Fat Prince.
