"Personality Runes" by Jean Hopkins
This book outlines the 25 Elder Futhark runes (including Wyrd), for use in finding out more about those around you. They're intended as guidelines, not absolutes. Just keep in mind that people have a tendency to grow and change!
There's also a short guide for creating your own Runes, including a Rune bag.
