I don't know how you feel about Thomas Ligotti, but he's probably my favorite living horror writer conceptually (if not stylistically). I place him in the elite category of genre writers whose cosmology and analysis of perception are as influential as they are original.*
This deal -- $1.99 for two of Ligotti's earlier collections in one volume -- is available from the following booksellers:
Amazon
Kobo
Google Books
Until now, this edition has been priced at $18.00.
