I would actually strongly advise against reading. Vicarious entrepreneurism is a real trap. It's better to start building or selling something. If your friends have any flair for business at all, tell them to open up a Shopify store and sell something. I actually recommended this to a friend who asked me the same question your friends asked. She's got a growing online jewellery business now. And she's keyed into the startup literature when she needs it.
