Thanks to somebody I just met on the ACA Discord server, I have been shown the following link where an author by the name of Jeremy Robinson is currently giving away five books for free during the Covid-19 confinement. All that you have to do is click the download link. If you join his email list, you get a sixth book for free. Now, these books appear to be the kind of genre which I no longer really partake in since a few decades, but I felt it might be interesting to check them out and share as well.
