The book 'The Origin of Vampires' contains a few spelling errors. It also contains some run on sentences and excessive comma usage, for example:

"Given this, vampires might have been the intended inhabitants of the Arenal trap and a mockery of our ancestors: undying predators that would live in an ever-shifting environment, consumed by their one base desire, eternally trapped in conflict, forever lesser than those that died to create them, killing and killing and killing to the endless laughter of a mad god."

I've linked a google doc to point out some obvious errors.
