Miss Sally's Unsuitable Soldier - Bluestocking Battalion, #3

She's never run from anything...except love. Luckily, her soldier is up for the chase. Practical Miss Sally has no interest in ballgowns and parties, which is why she's not exactly thrilled when she's summoned to play nursemaid to the Earl of Elwood. But the old man has made it clear-he's hosting a house party, and she's expected to attend.  If only assisting the earl didn't entail socializing with the guests.
If only those guests didn't include the earl's youngest son. If only that son wasn't a handsome and charismatic soldier dead set on wooing her... This is a sweet, clean regency romance with a standalone romance. There is an overarching plot, however, so the series is best read in order.
