Hell's Heroes, being the final book in the Demonata series, I had some expectations for it and I was a little disappointed. The majority of the book seemed like a filler for the big event at the end.
The story was interesting enough. It wasn't anything surprising or anything like that. There was only one part at the end that I was a little surprised about.
Kernel is still my favourite character and Bec is my second favourite. I don't really like Grubb's all that much to be honest.
To be honest I felt that Hell's Heroes was just a book. It wasn't anything special at all. But if you're a fan of Darren Shan's other books then you may enjoy Hell's Heroes. But as far as endings to series' go Hell's Heroes wasn't too bad.
