Yeah, there’s a pretty long list. My “to be read” pile grows constantly.
I’m going to go with something a bit left-field.
In the 1970s, Donald F. Glut (probably best known for eventually doing the novelization of The Empire Strikes Back) cranked out a series of pulp paperbacks featuring Frankenstein’s Monster. A few years back, a friend of mine, Bill Cunningham, via his company (Pulp 2.0), signed a deal to reprint them. The first volume, collecting the first six novels in the series, came out in 2014.
I immediately put it on my Amazon Wish List. Classic horror movies and monsters was one of the earliest things I was a fan of, and I still eat this stuff up. Plus, published by a friend of mine. But, four years later, for various reasons (most related to being too busy with other things), I have yet to pick it up, and so it still sits on my list…now joined by Volume 2, which collects the last six books in Glut’s series, which Bill just released.
So, in a way, this entry is a reminder to myself to get on that, as soon as I feel I have the spare funds.
