As Limbo falls, a new prisoner emerges from the Forbidden area cave of the Seventh Circle. The demons are closing in on the dwarf Clavius and all allies of the fugitive prisoner. Chiron is pressed to control the unrest by his centaur kind against the newly arrived humans to his circle, and the miners join the ranks of the fugitives while attempting to assist Clavius and the newcomer, John Moore, who has been caught up in the tumult against his wishes. A new guest, and a more ancient fugitive of Hell arrives at the river Phlegethon, throwing off the fragile balance of Chiron's circle once and for all. In the midst of the chaos, a connection between John Moore and the new prisoner is revealed, and new allies are found in the journey to escape Hell. Can they make it or will the Fallen discover their attempt at freedom? This is Book IV. Book V, the finale of The AngelFall Series will be available in June 2013.
