Great debut by a new author. This is unlike anything I have ever - starting out as fantasy then delving into sci-fi, post apocalypse. Just had a few minor problems for me though - apart from Jorg no other characters are developed and I like my world building in fantasy novels which incidentally is not required but I would have liked to read a bit more about this world.
This book just races along nicely. A word of caution - the book has its share of violence definitely not for faint hearted as the main character is just 13 and killing, raping comes easy for him - its a harsh world.
Must read for grim dark fantasy readers.
