Thank you very much for this wonderful share. I can now add a few extra goosebump-generating titles to my rapidly growing collection. Max reps, batman1101.
UPDATE: I just did a Google search with these keywords and found more downloads:
books.bookfunnel.com/* Horror
You can change up the keyword Horror to anything you want.
Earlier, I posted another link for sci-fi e-books but learned after-the-fact that the freebie offer had expired and the books were available only at cost on Amazon; so I removed it.
