Pretty much a straightforward question. I have only two books by KB left to read, Kissing the Rain and Martyn Pig...then the wonder ends. And I get through his novels typically in a few hours, 1 day max. So I'm on the hunt for similar authors until he comes out with his next book. Suggestions?
check out http://www.goodreads.com/ if you add and rate the books you have read, it will start giving you recommendations based off of those books. I have found it to be pretty useful.
I know you want authors similar to Kevin Brooks but I must recommend his book Being. It is another one you could probably get done in a day or so but it is by far my favorite book of his and pretty high up on my list of favorites all around.
