Samantha is in quite a tangle. Her father is dead and her gambling rogue of an uncle is running their estate into the ground with his carefree spending and losses at the tables. Sam tries to warn her uncle that they are on the brink of ruination, but he refuses to listen to his ward. Their only hope is the continued success of their famous stables. But, to Samantha's horror, she finds out that her uncle has recently bet the pick of their stables and lost. If the winner makes the obvious choice and takes their famous stallion, Black Knight, then the family will lose almost all of their income.
Samantha is determined to hate the handsome lord who has come to take their livelihood, but he turns out to be nothing like she expected. He is a gallant gentleman...and he actually prefers Sam to her stunningly beautiful sister, Emily. When he offers to let Sam keep Black Knight in exchange for coming to London and keeping the matchmaking mamas off his back by pretending to be his soon to be announced fiancee, it seems to good to be true. And it is...because Sam has done the most foolish thing imagineable. She has fallen in love!
