Here’s one of those books that uses its title to explicitly tell you what you’re getting - a collection of stories featuring all things squamous, cyclopean and antediluvian:
Lovecraft’s Monsters.
Filled with a variety of tales that revolve around amphibious people, trans-dimensional head-fuckery and things that go
Tekeli-li in the night, this is a solid (if perhaps not particularly exceptional) anthology that will mainly appeal to readers already well-versed in Lovecraft’s originals. There’s a very wide assortment on offer here: from poetry, to comedy, to a story that bizarrely acts as a sequel to both
At The Mountains of Madness and Mary Shelley’s
Frankenstein.
If you’re already an established fan of H.P.L., then you’ll definitely find something worth your time amidst this collection, just don’t expect to love every last one. Those as of yet still uninitiated with the Cthulhu mythos may be best served starting with the original stories before progressing any further.
