By Louise Allen

On Sale: 2/24/2026
A hidden-identity, high-society Regency romance 

She’s a mystery 
that the duke will solve! 

After fleeing the ton in ruin, Lady Catherine Brandon built a new life in sleepy Oxfordshire. Her secret past means anything beyond an acquaintance is out of the question. So, the arrival of Quinn Falconer, the Duke of Harland, threatens everything when their startling attraction becomes recklessly tempting… 

Though Quinn has ambitions for the town that borders his newly inherited estate, Cat is diverting all his attention. With the grace of a high-society debutante and the gumption of someone who’s known hardship, she is a compelling contradiction. And the more he investigates, the stronger the pull toward her…
