How does Free Book Friday work? Here's what the website says:
It's simple. Every Friday, we give away free books!Go there to sign-up to win!
That's right. Each week, we feature a new author with an exclusive author interview podcast or written Q&A and host a drawing to win free signed copies of his/her book.
All you have to do to enter to win each week is sign up using the entry form. Winners are chosen at random and posted on the site every Friday morning. Hence the name, "Free Book Friday!"
