I would be interested to know if there was a 'gold standard'/'bible' of finance books for someone who knows very little, but doesn't mind a technical read.
This isn't general finance, but 'The Intelligent Investor' by Benjamin Graham is recommended a lot - some of it's uninteresting, but there are a few really useful/interesting sections!
In terms of Company Valuation (for cash flowing companies, not startups), the bible in that world is "Valuation (McKinsey & Co)"
