Philippa Gregory, the author of "The Other Boleyn Girl", will be at the Brorders bookstore off Preston and Royal tonight at 7. Unless you’re way into historical novels, you probably only recognize this title from seeing it in recent movie trailers. A big screen adaptation of the book opens in theaters this Friday. The plot is centered on two beautiful sisters, played by Natalie Portman and Scarlett Johansson, who compete for the love of King Henry VIII, played by Eric Bana. If you’re a fan of Gregory’s literature, or if you just want to pick her brain about the celebrities they cast for upcoming movie, now’s your chance.
