You couldn’t design a better hero than the very eligible and extremely charming Earl Grantham. Unless, of course, you are Margaret Gault, who wants nothing to do with the man who broke her youthful heart.

Widowed and determined, Margaret Gault has returned to Athena’s Retreat and the welcoming arms of her fellow secret scientists with an ambitious plan in mind: to establish England’s first woman-owned engineering firm. But from the moment she sets foot in London her plans are threatened by greedy investors and—at literally every turn—the irritatingly attractive Earl Grantham, a man she can never forgive.

George Willis, the Earl Grantham, is thrilled that the woman he has loved since childhood has returned to London. Not as thrilling, however, is her decision to undertake an engineering commission from his political archnemesis. When Margaret’s future and Grantham’s parliamentary reforms come into conflict, Grantham must use every ounce of charm he possesses—along with his stunning good looks and flawless physique, of course—to win Margaret over to his cause.

Facing obstacles seemingly too large to dismantle, will Grantham and Margaret remain forever disconnected or can they find a way to bridge their differences, rekindle the passion of their youth, and construct a love built to last?
