Demon Thief

Demon Thief is a book in Darren Shan's Demonata series. Though it is the second book in the series, it is a prequel to Lord Loss, the first book in the series. The protagonist is also different from that of the first book. The narrator here is a new character called Kernel Fleck, as opposed to Grubbs Grady, the protagonist of the first book. Demon Thief takes place about thirty years before Lord Loss so most of the characters from the first book did not appear, though a few did. It was also actually the sixth book of the Demonata to be written, although it was the second released.
