Fierce Women of Science Fiction, Fantasy & Horror from Humble Bundle is a bunch of novels and novellas from Open Road Media. Although there are novellas in the bundle (which are about 1/2 book size) there are also omnibus volumes so I guess 65 items is fair. One thing about looking at the omnibus images those must be generated art as the Witch World books are quite different thicknesses but look all the same in the images.

The bundle is $18 and includes:

The Iskryne series

• A Companion to Wolves (Sarah Monette and Elizabeth Bear, 2007)

Parasitology

I didn't sort the rest as I realized this is too much stuff to buy. I'm only really interested in Witch World books which for $18 would be a good price but I also don't want a bunch of stuff I'm going to virtually toss.

Mind you if this were a comic book collection or a table-top RPG collection and the same scenario I might still buy it. But for novels I feel I would try to read many of these and waste my time.
