Wellesley College grad Uzuri M. Wilkerson (center) had a book party at Tres Gatos the other day for “Sour,” the second installment of her “Bitten” series, which is about sexy vampires (and the sexy people who hunt them). Wilkerson was joined by friends and fans, including Allison Wright (left) and Hope Freeman.
