Waltzing with the Earl

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
A wallflower's time to shine… 

The Earl of Shalford needs to marry into money to save his estate. Wealthy and beautiful Henrietta Buxted should be the perfect candidate. So why does his eye keep wandering to her quiet cousin, Charlotte Wyncroft? 

Charlotte watches Henrietta's games of courtship with wry amusement. That is, until a stolen dance reveals a hidden side to the earl. Penniless Charlotte knows she's far from a suitable match, yet, in Adam's arms, she can dream of the happily-ever-after she's always wanted!
