Not quite free books, but ...

Do you know about http://www.thefussylibrarian.com? If not, you should. The librarian send out an email daily letting readers know about discounted ebooks. They're not always new, but many of them will be new to you. And tomorrow – June 16 – one of my books will be featured. So if you sign up today, you'll get the email tomorrow... It's free, of course.
