"Heating His Blood" by Zach Morgan

This novella follows the classic "Dracula" with Jay Harper (Jonathan Harker), a real estate agent, traveling to a remote mansion to try to make a deal with Vukomir Korolenko (Vlad Dracul).  Most of the story proceeded quite slowly until Vukomir makes his move to relieve Jay of his blood; that's where it takes a hard left turn from the tale it is based upon and lands with an interesting ending.  79 pages (Kindle edition).
