Spring, 1905: Free-spirited like the Thoroughbreds she rides across the Kentucky countryside, Stella takes adventure by the reins when she's asked to attend a mysterious wedding in rural England. But once she arrives at the lush Morrington Hall estate, her cold and ambitious father confesses that he won't only give away his best racehorses as gifts—he has also arranged to give away his daughter as bride to the Earl of Atherly's financially strapped son . . .

Stella refuses to be sold off like a prized pony. Yet despite a rough start, there's something intriguing about her groom-to-be, the roguish Viscount "Lyndy" Lyndhurst. The unlikely pair could actually be on the right track with each other . . . until they find the vicar who was to marry them dead in the library.

With culture clashes mounting between families, a scandalous murder case hangs over Morrington Hall. Now, Stella and Lyndy must go from future spouses to amateur sleuths as they team up to search for the truth—and prevent an unbridled criminal from destroying their new life together right out of the gate . . .
