From the unexpected high bills

If you already know K.Dick (which I strongly wish you) or you do not know the (happy you are, on the verge of discovery!) This collection of stories, to my knowledge unpublished, should challenge you.
They are very revealing indeed of K.Dickien universe while dual perceptions, typically that of a human - more or less powerless before events - the face of a surprising alien creature precisely by his perception and also ... its decisions.
Also, these new, ten, materialize here is a science fiction reader looking for: a demanding writing, frequent episodes, visions of very different reality and a fall in the image of the glove that one turns. Therefore, very surprising.
Note that here they are often focused on metaphysics.
K.Dick is known for novels such as "Ubik", "The Three Stigmata of Palmer Eldritch." He was also a great novelliste. You'll here the flagrant proof. And like me, the moment I have - unfortunately - too short to complete this collection, you'll want only one thing, start another.
Excellent trip to you!
