Solid reading/literature for investment/retirement/income taxes?
Something that introduces the vocabulary and treats the reader like an intelligent individual? It's a bit overkill for 'retirement', but Yale has a free online course in Financial Markets. It's very light on math, but does a good job establishing jargon and its history. It covers most of the things you'd buy or sell in financial markets, and is presented by Nobel Prize winner Robert Schiller. This particular series was filmed in 2007, so it also offers a good historical perspective of the start of the subprime collapse. There's a number of high profile guest speakers as well. I would encourage you to think critically about their speeches though. If you research what's happened to them after that lecture, it's quite entertaining: one IPO'd a 'private equity' firm that underperformed the market as a whole, another hedge fund manager bought an airline with a partner firm that was arrested for running a ponzi scheme six months later.  The reading list in the syllabus make a pretty good introduction to the field, but keep in mind they're for institutional investors not your 401(k).
