Monstrum is an anthology of 20 classic short stories involving a variety of monsters from myth and imagination. From ghouls to sirens, cannibals to rat-people, there are plenty of creepy creatures to unsettle a few evenings of reading. One story, "The Cube," is worth highlighting, as it is a precursor to the "pod people" science fiction trope, involving identity take-overs by strange doppelganger creatures.
