Etta Moore expects nothing more from a Tuesday than another dull day in the office. But when her morning commute ends in Regency England, she is forced to accept the impossible: she and her ancestor Miss Henrietta Bainbridge – or ‘Mad Hetty’, as she’s known amongst the ton – have switched bodies.

Suddenly Etta and Hetty must get to grips with the new worlds they find themselves in. For Etta, it’s goodbye to dating apps and the daily commute and hello to the list of things ‘Ladies Do Not’ do. Luckily the dashing Lord Stanhope is on hand to aid her through even the most shocking of faux pas.

Meanwhile Hetty, who has always felt unseen and unknown, finds her truest self blossoming with the help of 21st century medicine and the most welcome attentions of her rather beautiful Adult Learning teacher, Stella.

Two hundred years away from everything they’ve ever known, might Etta and Hetty have actually found a place where they each truly belong?
