Apart from an epilogue/conclusion this is written entirely in the form of letters. Lady Susan is recently widowed and in the possession of a 16 year old daughter she considers stupid and hateful. Susan is already the subject of much scandal and gossip (having nearly split up one marriage, and managed to break up another engagement through flirting), before she descends on the house of her brother in law for a stay as she believes she has no where else to go until the scandal settles.
Meanwhile she tries to get a suitable marriage for herself whilst trying to get her daughter off her hands by making whatever marriage agreement will suit.
Even more scandal erupts when her sister in law’s brother appears and decides he is in love with her, despite the rumours. Soon however, Susan is back in Town and through various schemes married and her daughter off her hands.
Interesting way of writing a short book, which I believe was one of the first Austen wrote, but never submitted for publication. The main character is entirely mercenary, never out for romantic love either for herself or her friends. She’s only out for a suitable marriage and will be entirely two faced to get what she wants. Cant think of another character like her.
