Query: A Very Good Book If Your Shipwrecked

This is a very good book if your shipwrecked. It teaches you how to cook a snake, make your own compass, tell how to know which fruit to eat, and many other useful things. This book is wonderful and I hope I have it with me if I get shipwrecked! YOU should get it and don't prove me wrong.
