My husband was unimpressed by the Hal Spacejock sample chapters he read two of them). I just read the first one this afternoon, and have yet to form an opinion. It wasn't great (funny) but it wasn't horrible either.
My 2nd choice, however, cost more than I'd like to pay. I find 12.99 to be expensive, especially for an e-book (and no I do not buy hardcovers either).
So as of right now, I don't know what to vote for, but I'd hate to miss out on the book club two months in a row.
