That would be Create A Character Clinic by Holly Lisle and Way of the Cheetah by Lynn Viehl (known in the blogosphere as PBW), both e-books are available now on Shop.HollyLisle.com.

Create A Character Clinic is a step-by-step course for creating characters who will come to life in your fiction. Holly walks you through the process she uses. She readily admits something different works for everyone, but her process is easy to follow, her tone is conversational, and the book is encouraging. If you’re a fiction writer who wants to write more alive and complete characters, you owe it to yourself to get this book.

Lynn has posted Way of the Cheetah posts regularly on her blog. People have begged for more. Way of the Cheetah is Lynn’s answer to those requests. She, too, has provided this in a conversational voice designed to be an easy, enjoyable read. Yet it’s chock full of useful information to help you streamline your writing process. And she maintains the cheetah metaphor throughout the three part book: Eye of the Cheetah, The Writing Savanna, and Running Down the Story. Are you a writer looking for ways to boost your productivity? Way of the Cheetah is worth your time.

And Holly’s got one more thing, whether you buy these books or not. She has an affiliate program that pays you for books people buy or for people who sign up for the affiliate program through a link on your site.
