Shannon Hale's Austenland doesn't involve zombies -- it's the one about a woman with an unsatisfying love life who takes a vacation at an Austen-themed country house/amusement park, where some of the other guests are fellow tourists and some are actors and everyone has to stay in character as Regency people. I kind of enjoyed it, and I actually think it might make a good movie if the screenwriter was clever. (By contrast, I can't imagine how P&P&Zombies would ever make a good movie -- I'm not sorry that project seems to be moribund. . .)
