This book does strange things to you... You read it in one draught, because its story is so suspensefull, and the next day you remember next to nothing of it. Yet at the time of reading, everything seems crystal clear... Your cognitive processes become warped, altered to fit the twisted passage of thought of PKD.
Even though this book has almost nothing to do with VALIS, they produce this same effect on you, as if you had drunk absinthe.
Explore the dark corners of mind and thought and possibility...
