Books That Disappoint—what to do?

Some books make you wonder why the author bothered...and then make you wonder why YOU'RE bothering. Do you continue with a disappointing book...or put it down?

I've done both recently. I picked up Jaimy Gordon's Lord of Misrule on the basis of its solid reviews. But Gordon's prose felt so clogged and overworked it was offputting. It turns out Gordon is a professor of writing, which maybe is why the book feels a bit like a writing-class exercise. I love dense, rich prose, but not.... Well, anyway, I put the book aside.

Then I picked up Sara Gruen's newest, Ape House, in which a family of apes—who communicate using American Sign Language—eventually become stars in their own reality tv show. Just think of the possibilities! But Gruen's prose is thin and screen-writerish. And her apes turn out to be a lot more interesting than her humanoids.

I finished Gruen's book, though—thinking there might be a payoff. Besides it wasn't painful to read. And there is a sort of pay-off at the end, predictable but sweet.

*Added later...For a truly great read about apes and people, try The Evolution of Bruno Littlemore (sorry, no reading guide)...it's brilliant, funny, and  disturbing.
