For the first time in a year, I’ve lost myself in a book. It’s Barbara Kingsolver’s latest, The Lacuna– a marvellous historical novel that centers on a Mexican-American who becomes cook and secretary to Diego Rivera, Frida Kahlo and Leon Trotsky. I’ve disappeared into the world of mid-century revolutionaries and artists, surfacing into my own life with that lingering distraction that comes from having half of my head, and even more of my heart, ensnared in a fictional world.
