Ebulon, the last human city, is under attack by the largest confederation of orcs ever assembled. Against this monstrous force, there's little hope of surviving—save that their King has a most unique ability. Knowing that his brave troops cannot protect his city on their own, he calls for aid across all worlds, desperately hoping that his pleas for help don’t fall on deaf ears. Answering the call, heroes from other worlds rally to offer their aid. But even with their help, victory is far from assured as the drums of war haunt the air. The battle is about to begin. 15 authors bring characters from their collective works together in this epic crossover anthology, creating incredible stories of heroism, selflessness and bravery.
