Charlie Jonquil is mild-mannered and kind―except when it comes to his one true adversary, Artemis Lancaster. Though Charlie has a brilliant mind for mathematics, Artemis poses a problem he can't seem to comprehend: how can one be so lovely and so infuriating? A party in London brings him into the company of the maddening young lady, and it is clear that Charlie's disdain is mutual. But when an unfortunate incident between the pair involving Charlie's jacket and a glass of raspberry shrub leads to scandal, the sworn enemies are left with only two options: be ruined or be married. So it is that Artemis finds herself in a most outrageous predicament: she must wed a gentleman she's hated for years―and she pledges to avoid him at all costs. But it is only when they enter into this mockery of a marriage that Charlie and Artemis learn things are not as simple as they once appeared. As their tentative ceasefire leads to friendship, it seems their marriage born of desperation might lead them to a love that was destined to be.
