Our book club chose Kurt Vonnegut's Timequake to read this month, and I approached it with such high hopes. I was sooooo disappointed. I finally gave up on page 190 or so. Basically, it's a quasi-memoir/sci-fi novel with what could have been a very interesting premise - a glitch in time causes everyone to "reset" to ten years prior, after which they must repeat the exact same ten years (with no changes - doing only exactly what they did before, be it mistake or no). Everyone knows they are "repeating," but they can't do anything to stop it or change it.
All the way, Vonnegut makes social and literary points that are in themselves valid, but there's no real cohesive, larger story to pull everything together. There are no primary characters with any discernible plotline. There are no objectives. There are no central conflicts. It's just sort of a wandering, stream-of-consciousness . . . thing. (I hesitate to even call it a narrative.)
Sooooo, anyway, unless you are a big Vonnegut fan (as I've heard that this novel is very indicative of his work, though not his best book), pick this up. If not, pass on it.
