Friday's Child — Georgette Heyer

Rejected by the woman he deeply craves, the incomparable Miss Milborne, for his unsteadiness of character, wild Viscount Sheringham is bent on avenging fate and coming into his fortune. Rebellious young Sherry could not gain his inheritance until he married, he leaves his mother's house and on a passionate impulse, he vowed to marry the next woman he saw. But the very first woman he sees is his life-long friend Hero Wantage, a young and charmingly unsophisticated girl. To orphaned, pixie-ish Hero, who has secretly loved him since childhood, it seemed like a star-studded dream when dashing Lord Sheringham asked her to be his bride--for although she knew it was a marriage of convenience (his convenience), it eliminated the depressing prospect of life as a governess. It seems that this marriage might solve all their problems.

Back in London, Hero soon discovers the glamorous social scene and strives to make a name for herself among the right circles. But their marriage soon became a frenetic comedy of errors, as Hero tried to keep up with the fashionable and very unfamiliar society in which she now found herself. From chariot races to gambling tables to exclusive drawing rooms, an exasperated Sherry followed in his wife's wake, trying to clear the air after her well-intentioned but scatterbrained escapades. But when Sherry intervenes, fearing she'll embarrass them both, misunderstandings pile up, friendships are tested and hearts are pushed to breaking point. And it was with great surprise that both Hero and Sherry discovered that even a marriage of convenience can turn into a love affair, under certain circumstances....
