William Boyd has moved to Bloomsbury for his next novel. The British author, who was at HarperCollins, will release Sweet Caress with his new publisher in September 2015.

Bloomsbury, which took world English rights (excluding Canada), from agents Jonny Geller (at Curtis Brown) and Amanda Urban (at ICM Partners), will be releasing the title in the U.S. and U.K. simultaneously. Alexandra Pringle, who acquired the novel, said Bloomsbury "couldn't be more ambitious for this," and called the work "Boyd's most beautiful, daring and enthralling novel to date."

Geller, who echoed Pringle's excitement by proclaiming the novel will be Boyd's "biggest book yet," explained that the work is "a sweeping story of a remarkable woman photographer’s life through the turbulent 20th century."

The book's heroine, Amory Clay, is born in Edwardian England. Tracing her life from her early childhood, through her years in boarding school, the novel follows her as she traipses through 1920s Berlin, 1930s New York and London, and on to France during World War II. In France, Clay becomes one of the first female war photographers.

Boyd has written 12 novels and won numerous literary awards, including the Whitbread and the Costa. His most recent book, the James Bond novel Solo, was published by Harper last year.
