There aren't many books that keep you up through the night, just becuase you can't put it down, but this is one of them. I read this is an incredible ten hour straight sitting, a first for me. It was the combination of great characters, an unfolding tale that I couldn't wait to see what happened next, and a setting that really scared the pants off me. I haven't read all of Gray's books, but I'm going to now. You have to buy this, if only for the bit when the hero has to journey through the rubbish hold. Scarier than anything else I've read for years.
