The Poopie Suits and Cowboy Boots series of nonfiction submarine books is a collection of seven thoroughly researched books packed with the stories, history, and color of the US Submarine Force. The authors, brothers Charles and Frank Hood, put their money where their mouth is by donating the first $50,000 of book royalties to the USSVI Charitable Foundation. All books are available in softbound and e-book formats exclusively at amazon.com. Two of the books have been named to The Book Authority's all-time top-20 submarine books and are also available as Audible audiobook selections: Poopie Suits and Cowboy Boots and Sub Tales. More than a half-dozen of the original stories from these books have been featured in the quarterly magazine American Submariner as well. Check them out!
