There is nothing more fascinating than a darkly handsome rake, especially one as controlled and elusive as Dillon Caxton, protégé of Demon Cynster. Despite his dangerous air, Dillon is now a man of sterling reputation, but it wasn't always so. Years ago, an illicit scheme turned into a nefarious swindle, and only the help of his cousin, Felicity, and her husband, Demon, saved Dillon from ruin. Now impeccably honest, his hard-won reputation zealously guarded, he's the Keeper of the Register of all racing horses in England. His standing and aloofness make Dillon undeniably desirable to young ladies, but despite all the lures thrown his way, he remains uninterested, his attention unfixed.
Until Miss Priscilla Dalling erupts into his life. A stunning beauty, she affects Dillon as no other ever has, but what fascinates him even more is that this tempting young lady is clearly desperate, and equally clearly lying about wanting to see the Register to fulfill the whim of an eccentric aunt.
Lady Priscilla Dalloway will do anything to see what's in the Register. Her twin brother, Russell, who had quarrelled with their father and quit the family home to work with the finest racehorses, has disappeared from Newmarket. Pris knows clues to his plight can be found in the tome Dillon Caxton protects so assiduously.
In its pursuit, she unleashes her feminine wiles on Dillon - to no avail. But Dillon is now determined to learn the truth behind her quest. Exploiting the powerful attraction that flares between them, he succeeds in convincing Pris to tell him all, to trust him with her twin's life. Together, Dillon and Pris locate Rus, only to discover that his life is threatened by the perpetrators of a massive betting swindle, from whom he's escaped.
The time is ripe for Dillon to repay old debts by helping another as he himself was helped. Assisted by Demon, Felicity, and Barnaby Adair, Dillon and Pris embark on a journey riddled with danger - and undeniable passion - as they seek to overturn the swindle and expose the deadly perpetrators. And along the way they discover the answer to that age old question: What price love?
