Hell's Horizon

Hell's Horizon is a novel written by Darren Shan, first published in 2000, with a modified version re-published in March 2009, with significant changes made by the author. It is the second book in Shan's The City trilogy, being preceded by Procession of the Dead and followed by City of Snakes. Shan published the book under a new pen name D.B Shan, instead of his other pen name Darren Shan, to prevent children from reading the book, as it is intended for adult audiences, unlike most of Shan's previous works. The story runs parallel to its predecessor, Procession of the Dead.
