Prudence and the Romantic Poet by Nina Clare

Miss Prudence Grace is very happy with her life. She lives quietly in the country among her sisters and their children. She sees nothing amiss with being a maiden aunt. She has no room for romantic notions in her calm, prosaic world. She has no hidden secrets, no glaring faults, or painful wounds. She wants for nothing. She is a very unlikely romantic heroine.
But an unexpected encounter in the sedate city of Bath upsets her predictable life. She is forced to spread her wings a little, meet new people, face new challenges, and discover that romance can strike most unexpectedly, and love changes everything.

This is a clean Regency Romance with plenty of humour and some dubious poetry.
It can read as a standalone, but many of the characters are from previous books, and it will be enjoyed best when read in series order.
