When Miss Poppy Garrison accepts her grandmother's offer of financial help for her family in exchange for Poppy joining the New York social season, she quickly realizes she is far less equipped to mingle with the New York Four Hundred than even she knew. As she becomes embroiled in one hilarious fiasco after another, becoming the diamond of the first water her grandmother longs her to be looks more impossible by the day. Reginald Blackburn, second son of a duke, is in New York to help his cousin find an American heiress who can help save his family's estate. But when his very proper British manners lead Poppy's grandmother to request he teach etiquette to Poppy, he quickly finds himself in for much more than he bargained for. And while they couldn't be more opposite, Reginald and Poppy just might find they have more to teach each other than they ever could have expected.
