If you are looking for Why the USS THRESHER (SSN 593) Was Lost by Bruce Rule and have found that it is only available on Amazon from 3rd party sellers, you can order it directly from the Nimble Books bookshop here for $24.00 plus actual S&H.
There have been quite a few transitions in my life since I founded Nimble Books in 2006, and along the way the Nimble Books website got caught in the shuffle. Since I do intend to keep operating Nimble Books for the foreseeable future, I am standing up the website once again. There is a ton of great content that I had available via previous iterations of the website that I would like to resurrect, but that depends on whether a) I can find my SQL backups (so far, no joy) and b) I can import them successfully (there were non-standard data structures due to plugins). In the meantime, content here will be sparse. I will begin with adding the current front-list books to the online store.
