looking for a good ruby book

I'm pretty solid on the rails framework, but I would like to focus on
the actually ruby language. does anyone know of any good ruby books?
Preferably for the rails developer?

Do you have the PickAxe book? It is pretty much the defacto standard:

Dave Thomas wrote the book with Chad Fowler and Andy Hunt. I think,
they're competent practitioners in ruby...
