Dark Fire of Doom (ebook) 

The Dark Man must search under the city for the magic fire, which is an evil gateway used by demons. Somehow, the Dark Man must close this gateway. Part of the incredible Dark Man phenomenon, this gritty and mysterious book will grip readers and pull them into the tense storyline. The sinister atmosphere and strong black-and-white illustrations will entice even the most reluctant of teen readers because the book doesn’t patronise, and accompanies the dark tales with a 'grown-up’ style. This is one of the shorter stories in the Dark Man series focusing on the top 100 frequency words.
