When her mother dies, outspoken and vivacious northern girl, Cassandra Trent is brought out by her mother's aristocratic family in London. Unlike her cousin Susannah, she's only putting up with this London season because she promised her dying mother. Sparks fly when Cassandra meets Simeon Giffard, whose mother has nagged him into proposing to Susannah, even though he doesn't love her. Cassie and Simeon argue, but they are attracted to one another. Will Susannah rebel against her engagement? Will Simeon admit how he really feels? And will Cassie stay out of mischief for once?
