This is the 9th book in the Demonata series by the best writer of horror, writing for children. He started with the Saga of Darren Shan, the best series on vampires I have read.
The Demonata series is terrifying at times and totally brutal and gory at others. This 9th book is no different.
Throughout the series beginning with Lord Loss the main character is Kernel Fleck and his master is Beranabus and together with a load of other beings they control the entry of demons from the Demonata world into our world and destroy them. Whenever demons appear there is brutality and gore for those who like that sort of stuff.
In this novel Darren Shan begins with Kernel Fleck having his eyeballs eaten out, a horrifying description but the key to the whole story. He replaces the eyeballs in the magical realm but doesn’t realise that this has been contrived by beings from the past called The Old Creatures.
A powerful new force called the Shadow has united all the demons for a big push on the forces that wish to destroy them and we have a battle royal on our hands.
Clever writing from a master of horror. Not for everybody these books but for afficionadoes there are none better. For your older mature reader.
