In the frosty heart of Regency London, American engineer Weston Whitaker has arrived with a singular purpose: to perfect his steam-powered inventions. But his reckless disregard for England’s stifling social codes earns him a notorious reputation as “Tall, Dark, and December”, putting his project—and his prospects—in jeopardy. Bound by blood to a powerful duke, West is reluctantly drawn into society’s gilded web, where every glance and rumor can make or break him.

Tasked with taming this brooding American is Lady Penelope, London’s sharpest etiquette tutor and a woman who embodies the very aristocracy West disdains. Yet, beneath her proper exterior, Penelope is as fierce and unconventional as he is, and West finds himself captivated by her bold mind and dangerous wit. As sparks fly between them, Penelope battles to remain detached, unwilling to fall for a man who could so easily unravel her carefully constructed life.
