3.5 stars, rounding up to 4. This is a lot of fun - two kids run away from home, but they're running toward as much as away... toward the Metropolitan Art Museum, and they squat there for the better part of a week, dodging security guards and learning as much about art as they can. Because naturally, dogging the footsteps of docents is the best thing to do if you're a kid on the lam. They're such enjoyable children to read about, too, and the whole thing's so entertaining. I love that they think they've solved the puzzle about the Michelangelo statue and it turns out, nope, all the competent adults already know the information the kids have discovered, ha! So often stories like these turn all characters over 12 into shambling idiots but here everyone is an art nerd and they're all interested in sculpture together. The book does skim rather unbelievably over the whole deal with the poor parents (whose only crime seems to be making the ungrateful duo do chores like setting the table for dinner, the horror!) but to be fair, I'm more interested in what's going on in the museum too.
