The Stoat and the Debutante by Laura Greenwood

A stoat shifter heiress is sent to London in the hopes of catching a suitor.

Miss Harriet Ermington knows that as an untitled heiress, being presented to the Shifter Queen is an opportunity she can’t let pass, even if it means living under the control of her aunt.
With his family almost in financial ruin, Mr Frederick Stoaly knows he is expected to find a wealthy wife, even if his heart would rather find a lady whose company he enjoys.

The two of them find themselves drawn to one another despite believing there can be nothing more between them, but what happens when they discover how wrong they are?
