If you enjoyed the Bone Garden, give Peter James a go. First books a few years ago are not so good. Then he changed completely.
His latest books are about a detective in Brighton.
First one was DEAD SIMPLE. My heart rate increased by so much just on the first few chapters. My sister could not read that part. She got her husband to read it and tell her what it was about.
He has written a few more since then and I have enjoyed all of them.
