Dukes Prefer Bluestockings

Charlotte Butterworth is not looking for a husband.
She’s far more interested in numbers than suitors—and thanks to a rather dramatic (and possibly mistaken) doctor’s opinion, she’s quite certain she won’t need a husband anyway. Marriage, love, and happily-ever-after simply aren’t part of the plan.

Callum Montgomery, Duke of Vernon, has been engaged since childhood.
He’s charming, titled, and wholly opposed to marrying the daughter of the man he believes destroyed his family, betrothal or not. In need of a temporary reprieve, he proposes a marriage of convenience to Charlotte. No expectations. No future.

It seems like the perfect arrangement.
Until it isn’t.
