I won't claim to be permanently transformed, but I grok Lisp (and functional programming in general) fairly well.

If you're interested in functional programming in general, I find that learning XSLT (which is a functional language) is both enlightening and practical, it's also pretty fun, especially with XSL-FO thrown in for grins.

That said, here are a couple books for Lisp that I recall as being acceptable.
Fair warning: I think all or nearly all of these are now out of print, but you might find them used at Amazon or in a used bookstore.
