You may or may not know this about me but I published a book couple of years ago on how the average layman can stay safe online. Initially it had a pretty narrow distribution, you could get it on Amazon or you could special order it from your favorite bookstore.
I have now broadened that distribution significantly. You should now be able to get it pretty much everywhere. For all the places you can buy my book check out https://books2read.com/infosechelp. BTW there are three more distributors that are still working on listing my book on their site.
In addition to all those place it is also available from https://leanpub.com/onlinesafety where you can pay what you feel is fair.
You can also still special order it from your favorite bookstore. Here are ISBN and the editions that are available with old fashion brick and mortar bookstore distributor.
