I've been rereading some of the stories in Harlan Ellison's groundbreaking Dangerous Visions anthology and came across Philip K. Dick's 'Faith of our Fathers.' This sent me back to Dick's own collected fiction, spread across five volumes that appeared towards the end of the 1990s.
Prompted by my re-engagement with those stories, I've posted a review I wrote of the first three volumes--Beyond Lies the Wub, Second Variety, and The Father Thing--on my review page here.
The review was first published many moons ago in the pages of The 3rd Alternative #23, the original dark fiction magazine from TTA Press that later morphed into Black Static.
Those first three volumes were followed by two more - Minority Report and We Can Remember it for you Wholesale, the title stories of which were the source for the Spielberg film of the same name, and Paul Verhoeven's Total Recall.
I hope the review will send you back to these outstanding and genre-busting stories.
