Here are some popular writers on personal finance you can read on Amazon (before buying second hand at £0.1 plus postage). if, like me, you are taking a fresh look at your finances. You can actually read quite a bit of some of them without any purchase at all...I've picked up some useful tips just by browsing, and most of these authors also have blogs and/or websites.
Martin Lewis, Suze Orman, Alvin Hall, Jean Chatzky, Vicki Robin, Robert Kiyosaki.
From Robert Kiyosaki's Rich Dad Poor Dad I learned how to make a balance sheet and that my house is not an asset, strictly speaking, but a liability....who knew? All very interesting stuff.
