Hello,
I want to recommend all people the psychological roman "Animals" from Simon Beckett. It is one of the best and thrilling books, I read the last years. It is about a young man, educated by a prudish mother and a sexuel unrestricted father.
This contrast and the point, that he does not have an excessive intelligence leads his fate and the fate of some other people into a "hell of life".
He is catching unknown people by accident and after that, he will keep them....but I do not want to betray to much.
Read it!
