British author Gregson bows in America with her fast-paced second novel, an absorbing international period drama concerning three young Englishwomen and a troubled boy journeying to India in the late 1920s. The eldest at 25, Viva Holloway is an orphan hoping to retrieve her lost parents' personal effects; she's paying her way by chaperoning three younger travelers. Rose Wetherby is going to India to be married; Victoria “Tor” Sowerby is Rose's bridesmaid; and 16-year-old Guy Glover is returning home after getting expelled from school for stealing. Throughout, narrative shifts reveal the travelers' perspectives and fears: Viva is haunted by a childhood and family she barely remembers; Rose is growing increasingly nervous about how little she knows of her fiancé; and Tor is eager, after a disappointing deb season in London, to find a husband of her own and avoid returning to England. Guy's strange behavior makes it clear he's unstable, and before long, he's assaulted a member of a powerful Indian family, setting off a frightening chain of events for both himself and Viva. Gregson's rich imagery, strong characters and gripping plot make this a resonant page-turner. (June)
