I can recommend the anthology but "At the mountains of madness" is a tedious read as he (HP) goes into too much geology and such.

We need an abridged version that just cuts right to the shoggoths and such... whoa, kidding!
Geology is the least of my worries when actually reading Lovecraft, compared to serious political incorrectness and rampant (ab)use of the word "squamous"
