This month I've decided to throw my hat into the ring and nominate the latest release in the SF Masterworks range, Philip K. Dick's The Penultimate Truth.
I have no idea what this book will be like, but from reading the back cover it sounds a bit 1984ish (and if it's anything like Dick's other books I expect it to get pretty surreal!).
Once again you have a month to read the book, the thread will be opened for comment etc at the end of March.
