Her parents scramble to present her to the Duke of Wellesbourne; except he’s precisely the kind of rogue she has now vowed to avoid. Taking flight to avoid a match, Persephone runs straight into her would-be betrothed and pretends to be someone else. But dash it all, the duke proves to be irresistibly charming! If she remains in his company, she’ll end up in the wicked scoundrel’s clutches.
Even worse, her second attempt at escape lands her in increasingly poor circumstances. With nowhere to turn and her safety at risk, she may have to accept help from the one man who threatens her resolve—and her reputation.
