I wrote a novel about cargo submarines. Want to test read it? (For free of course.)

Hello everyone!

I spent my unemployed pandemic time writing a submarine novel. It has
reached a point where it is a complete and revised book, and it is now ready
for some constructive feedback from test readers. A novel is a kind of
submarine simulator, isn’t it?

If you are interested, you can one-click download a free copy in epub, pdf,
html, or markdown source-code format here:

And look! It comes with diagrams I made too!

Get ready for a whole new level of realism!
