Betsy Thoughtless is about marriage, rather than dealing with courtship and thus differs from the type of domestic writing that would develop in the 19th century such as Charlotte Brontë's Jane Eyre. Rather than attracting a partner well, Betsy Thoughtless focuses on marrying well and Betsy learns that giving way to the role of women in marriage can sometimes be fulfilling.

A story of love and adventure, following the fortunes of a young man and woman each trying to make their way in the wide world. Horatio and Louisa are twins, abandoned in infancy and adopted by a wealthy bachelor. For various reasons both leave his protection and set off independently: Plucky and determined Louisa must defend her virtue and make her way in a man's world, and her spirited brother seeks his fortune in the army. This energetic narrative gallops from city to court, from battlefield to convent, and across a number of European countries. Written in 1744 by actress and prolific author Eliza Haywood, this is an eighteenth century rollercoaster - action packed, passionate, melodramatic, and often unashamedly sentimental.
