Try use this signature. I hope this worked.

public class Author
{
    public virtual int AuthorId { get; set; }
    public virtual string Name { get; set; }

    private ICollection _books;

    public virtual ICollection Books
    {
        get { return _books ?? (_books = new HashSet()); } // Try HashSet
        set { _books = value; }
    }

    public void AddBook(Book book)
    {
        book.Author = this;
        Books.Add(book);
    }
}
