Query: 14 year old reader loves this book

Since seeing the movie U-571, I have loved reading about submarines. This book is great. I couldn't put it down. It is about the sister ships, the Squalus/Sailfish and the Sculpin. Carl LaVo did a terrific job on this book. Anyone who enjoyed Tom Clancy's SSN or U-571 will love this book.
