The best aspect about this collection is also its worst: Lovecraft needed to grow. This means that the initial stories and tales can be very tough, long-winded and over-the-top in the typical Lovecraftian fashion of writing. It’s only half-way that things settle into a better pace, tales become more comprehensive and gripping while gently building up an horrific atmosphere.
During the final third of the collection everything comes together and there’s a determination to the stories even though certain patterns become a bit too repetitive. Completely worth it though. Just be warned that at the start you may wonder what you’ve gotten yourself into.
