I don't think I can crow enough about Judy Tarr. No, really. She's one heck of a writer and also an excellent mentor. She loves to brainstorm worldbuilding and what's super cool is how she thinks a world through to implications you never thought of. Really.
Like, once there was this world and the men were extra large and the women were extra small. They'd selectively bred that way for many, many generations. So what does all that mean and what are the social implications? Judy knows.
Believe me, it's like talking to yourself, only better. (To quote my own character.)
So if mentoring is for you, try her out. If it works out, you've just discovered someone fantastic. Actually, even if you're not usually into mentoring, having Judy take a look at a novel draft and give you suggestions on how to pitch it or fix it might just be what it needs. She's only sold over 30 books, you know.
