This book is... Tough. The premise is interesting, looking at the goings on of a small society of doomsday-ers named The Seekers in the 1950s and their continuous struggle to believe their predictions as each message to them from their aliens turned out to be false (as in, nothing happened.)
This is not a Heaven's Gate style cult. No one gets hurt, just their pride and reputation. It's dry, but the desire to see the end keeps you going.
