In the climactic fifth book of The Shards of Excalibur series, Ariane, Wally, Flish and Rex Major are on a collision course, converging on the resting place of the final piece of the sword: the hilt, long ago removed from its original hiding place by the descendants of King Arthur. When Wally uncovers its surprising location, far closer to hand than they'd ever guessed, it seems all Ariane and Wally have to do is claim it and reforge the sword to defeat Merlin forever. Except... how, exactly, do you reforge a magical sword? Especially, how do you do it when the richest man in the world is on your trail and pouring all of his enormous resources into stopping you? When the pieces of the sword are at last reunited, the results aren't at all what Ariane and Wally imagined. With Excalibur whole again, the long-closed door into Faerie swings open wide. Who - and what - emerges from it may destroy everything and everyone Wally and Ariane have fought so hard to save - and allow Rex Major to snatch victory from the very jaws of defeat. Fighting side by side, Ariane and Wally must draw on all their strength, courage, magic and love to save the world...and there's no guarantee it will be enough.
