Must Love Breeches by Angela Quarles
She’s finally met the man of her dreams. There’s only one problem: he lives in a different century.
A mysterious artifact zaps Isabelle Rochon to pre-Victorian England, but before she understands the card case’s significance a thief steals it. Now she must find the artifact, navigate the pitfalls of a stiffly polite London, keep her time-traveling origins a secret, and resist her growing attraction to Lord Montagu, the Vicious Viscount so hot, he curls her toes.
To Lord Montagu nothing makes more sense than keeping his distance from the strange but lovely Colonial. However, when his scheme for revenge reaches a stalemate, he convinces Isabelle to masquerade as his fiancée. What he did not bargain on is being drawn to her intellectually as well as physically.
Lord Montagu’s now constant presence overthrows her equilibrium and her common sense. Isabelle thought all she wanted was to return home, but as passion flares between them, she must decide when her true home—as well as her heart—lies.
