Another book question

[FishHooks]

Whats a good book, that would help me read charts like cash flow, assets, all those good things like you would see on yahoo finance. Recently I've been helping my uncle with investment decisions, relating to index funds and how much should be in different types of indexs and assets. However i'm just looking to get more familiar with individual stocks, he's asked me a couple questions on those and coudln't give him great answers with confidence, just info on PE and net income things like that, but would love to really dig deeper into things regarding individual stocks.
