The Complete Writer's Guide to Heroes and Heroines: Sixteen Master Archetypes by Tami Cowden, Caro LaFever, Sue Viders
One of my writing friends recommended this book, and I’m so glad she did. I found it extremely useful in improving on characterization and character development.
This book discuses hero and heroine archetypes (ie the chief, the bad boy, the charmer, the lost soul, the crusader, the nurturer, and many others). It lists qualities, virtues, flaws, etc. for each archetype. It also covers layered archetypes (where the character has qualities of more than one), evolving archetypes (where it changes over the course of the story), archetype interactions, and much more.
This is another book that I highly recommend.
You can purchase it at all the usual places (Amazon, Barnes & Nobel, Books-A-Million), or you can purchase an autographed copy at Tami Cowden’s website by clicking HERE.
