I recieved an early copy from Peter. I have purchased all his previous works. Generally, I don't read short stories. I like long books, the longer the better. After reading Hello World I may have to update my reading preferences. Peter has a unique view on human nature and interactions. I find his works as a wonderful examination of the human mind. The science is extremely accurate and up to date, not fantasy. I strongly recommend all his works. Pay particular attention to his well developed characters and their response to unique situations. They are really showing how humans should act, or not. This is why I read his books and so should you.
