I remember when Carol Gino visited this board just before The Family was releassed in hardcover we had the opportunity to pose questions for her. Someone asked this and I thought it would be about 6 months, but I think she replied with it being maybe a year before a paperback cover is published.

Carol Gino was a trusted friend and companion of Puzo. It was Puzo's choice for Gino to finish his novel for him. Our own JG's Official Puzo's site explains all you'll need to know. Theres a link for it at the top and bottom of the page.
