This is a dense, thoughtful work, of lasting value, which will reward careful study. Hooks writes in an easily readable style, concisely and directly, about the most difficult and elusive portion of the art of character animation. Buy this book before you buy any other character animation title, or for that matter, before you choose software or other animation tools. You will find that Hooks' advice will also improve your script and storyboard development. One of the problems with books about computer-based character animation, such as my own "Character Animation In Depth", is that they lose value as the software they are written for becomes obsolete. Hooks' work will retain its value for a long time. Buy a copy, keep it handy, reread it frequently, and don't loan it to friends; you won't get it back. Give them a copy, instead. Highly recommended.
