Parallel III - Demon Hunters

Parallel III - Demon Hunters.
2011 edition.

Part 3 in the Parallel trilogy. George is back, and this time he needs Ken to do him a small favour... All Ken has to do, is to train the others in the art of fighting. A simple task and one that he relishes... But, as is always the case with George, Ken is about to find out that nothing is as simple as it's made out to be. Ken is forced to take a journey into the realms of complete madness, and there's nothing he can do about that because his family are going with him - without Ken, they will be almost defenceless. Through blood-sweat-and-tears, the story takes us on the final and most difficult test that Ken has ever faced.
