They never realized just how thin the line between hate and love could be...

until they tumbled over it.

Aubriella Penford is used to being an outsider in Regency London's High Society. Her love for science and lack of social graces set her apart from the other ladies of the ton, making her the odd one out at every glittering ball. So when her lifelong rival-and her brother's best friend-unexpectedly offers to help her through a Christmas house party, she's skeptical. Can she really trust the man who's vexed her since childhood? Even more surprising is that she accepts, setting the stage for an unforgettable holiday romance.

A scandalous wager, an unexpected snowstorm, and a daring rescue reveal a deeper connection than they ever imagined. As the season of joy unfolds, will their newfound bond lead to a Christmas happily ever after, or heartbreak? Escape into this heartwarming enemies-to-lovers Regency romance filled with festive cheer, sizzling chemistry, and a touch of holiday magic.
