Patience Whitford spent the last two seasons watching her elder sisters make grand matches. She is thoroughly apprehensive with the notion of being limited by marriage.

Their newfound freedom is threatened, however, when Issie’s great-aunt commands her to travel to London for a come-out Issie has never wanted. Issie, who is in poor health, is convinced she’ll drop dead like her mother did if she drops into a curtsy before the queen.

Charles Henfield stopped thinking of Henrietta like a sister when she was sixteen and he is determined to try his luck with her in London.

In Regency England, twenty-seven-year-old Leonora Appleby is considered by many – herself included – to be beyond her most eligible marrying years. With her childhood home, Hasterleigh Manor, soon to be taken over by the heir to the land, George Lockwood, Leonora has happily resigned herself to a quiet life as a country Miss.

But severing ties with her taciturn suitor isn't as straightforward as Sophie envisioned.

When their elderly guardian dies, Faith Whitford is determined to set up house in Bath and look for respectable country gentlemen for her four sisters. She has no ambitions for mingling with the ton.
