The print version is available in bookstores across the US & the world and, of course, on Amazon US, Amazon UK, Indiebound, Hive and many other online retail sites.
The book makes a good Christmas gift; just slip it in a stocking by the fire or in a nice box, with red, green, shiny Christmas wrapping paper & a lovely bow. It was so much fun to write & it will be fun to read.
In fact, you might also consider purchasing a copy of my first book H. P. Lovecraft & the Black Magickal Tradition & then giving both books as a gift. They complement each other & raise interesting speculations about magic, science, gods, goddesses, monsters, robots & artificially intelligent virtual reality entities.
Just the sorts of things to think about during this most festive of seasons!
Best wishes !
