The world is overrun with monsters called Nemeses-and a young boy infected by one will stop at nothing to defeat them all!

Evil creatures called Nemeses fall from the skies and the only ones who can fight them are Wizards-infected ones who survived a Nemesis’s corruption. Seth, one of these survivors, vows not only to fight the Nemeses, but to find their mythical nest, Radiant, and destroy it!

The battle for Caislean Merlin rages on. Queen Boadicee enters the fray at great risk to her own life while Seth’s friend Ocoho, of the Queen’s forces, wrestles with a shocking revelation about Mordred, her most trusted comrade in arms. Seth’s other friend, Melie, must deal with Liselotte, an Inquisitor who captured her while infiltrating Caislean Merlin. And Doc, Seth’s most reluctant ally, shows up with a couple of friends who could play a big part in the conflict between Inquisitors and Wizards.
