As many of you likely know, I published a pair of books in 2020 about our very own “On-the-Roof Gang,” the US Navy’s cryptologic pioneers. Thanks to you, these books have sold well and have garnered some amazing reviews on many online retailer websites. Since then, I have continued my research into the group, finding new information and new photographs that are pertinent to the story. I am very excited to announce that I have published a Second Edition of both volumes of the books.
