Grosvenor Square

Amid the genteel charms of 19th-century London's elegant Mayfair district, the Hathaways take up residence in Grosvenor Square. The close-knit family seems assured of a bright and comfortable future, but their idyllic world is disrupted by the arrival of Jasper Munroe, a distant relation who touches off a series of unsettling events that will change their lives forever. 328 pp.
