In the “Home” page there will be a registration form and log in/log out for the simple user and the admin of the web site.
In the “Author” page will be a list of author ,whith a photo for each one and a shori biography.
In the “Books ” page will be a list of last books and every books will be ralated to its author. User can commnet/like this book.
