One recommended a really short yet helpful book called "The Wealthy Barber." It explains all the basics of personal finance in the form of a folksy story. (It also makes a good gift if you know someone who's struggling with this.)
Another author who writes more detailed books: Venita van Kaspel. I asked my financial advisor which book of hers I should read, and the answer was "anything."
