Query: a great megalobook

THis was one of the best books about the legendary giant shark megalodon and I am a huge fan of this giant primal-great white shark like beast that once dominated the earth millions of years ago and this book can convince somebody that this shark may still be alive today. I have the other following novels besides this book. EXTINCT, MEGALODON(robin brown) MEG and the TRENCH(by Steve Alten) and I have this one other book called CREATURE By PETER BENCHLEY I'm not sure if there's a meg in the story but I will find out. Anyways I hope that there are more megalodon books to come out in the future I would look really forward to colleting all megalodon books.
