I brought the enormous third volume of Diana Gabaldon's Outlander series here to Mexico. It's working splendidly as escape from everything, whether on a plane, a bus, a hotel room, waiting. It might not work so well back in the US, but here, with my brain fried from going into my inadequate Spanish to communicate and understand, and my English going into others' inadequate English with which to communicate and understand, it seems a perfect escape. Just sayin'. Anyway, it's the only book I brought with us.
