...this confuses me. So...it's like tumblr...for books?
Either way, I'm mainly on Goodreads. I do occasionally come here, and also do periodically import my shelves from GR here, but GR is a more sure bet for contacting me.
I tend to see Derr's books (well, mostly short stories) as more of character studies than anything and this does not disappoint. The characters are so cute. I especially love the ending.
