Merciless Heir by Rebecca Baker

Fairytales aren’t real, even if his art theft investigator looks like a princess.

Kingston Sinclair has no need for a tiara or the unbelievable tales that have been spun around the lost family heirloom for decades. But sappy, romantic legacy aside, the jewels are worth a pretty penny, and money talks louder than tradition. He’ll take that stupid crown and sell it to the highest bidder…
That is, if he can find the damn thing.
When a stray bullet ended Sadie Hesse’s career as an agent in the FBI’s Art Crime unit, she began working as an independent art theft investigator instead. Problem is, art crimes are few and far between, so when she hears from the Sinclair matriarch about locating a long missing jeweled tiara, it sounds like the perfect opportunity to earn the cash she needs.
And who cares that the eldest son shows up to hire her too? Income is income, even if the two family members seem to be at odds and paying her for the same thing. But what happens once she finds what they’re both looking for?
Her investigation draws her closer to Kingston Sinclair than she would like, but she can’t help falling for the quiet, brooding man with motives she can’t seem to determine. And when they uncover an earth-shattering secret about his family, Kingston starts to question if those family legends aren’t so unbelievable after all.
But if the stories are true…then finding that tiara might put them both in danger.

If you love the savage sexiness of Nicole Fox’s dark romances or the forbidden loves of Sara Cate, don’t miss out on the fame, fortune, and lies of the Sinclair brothers.
