H.P. Lovecraft

I was recently thinking about how I'd love to have a book with me everywhere I go, but I don't have that many I want to read. I'll most definately check these out. Where should I start?

I just finished Steven Hawking's A Brief History of Time, amazing book, that guy is incredible. My next book will be "Plato and a Platypus Walk Into A Bar" suggested by my Philosophy teacher(I'm majoring in Philosophy.)
