Hey Unc. A huge house inhabited by Giants ?
(these are literally big people. Husband wife and four sons all stand at around 6'6" - when i sit in the chairs my feet only just touch the ground. i don't think i've ever stayed in such a big house)
I think you may have stumbled upon descendants of the Nephilum !
And as for the fridge...perhaps they just stock that for appearances. Maybe they prefer fresh human flesh.
And you say you're out there all alone........Spooky
Library sounds very interesting though ! Any books on werewolves or vampires ?
