The Black Unicorn (en Inglés) - Heather E-F Carter

1792. Revolution roars across France, the monarchy lies in ruins, and England edges toward war. Yet in London drawing rooms, Society is obsessed not with politics, but with a daring and elusive highwayman who stalks the roads-the Black Unicorn. 

Elina Brinkley has no time for fantasies. Freed at last from a brutal marriage, she is determined to claim the life denied to her and to protect the only people she loves most: her two sisters. But when their journey north to the Yorkshire Moors is violently interrupted and her sister is savagely attacked by one of the Black Unicorn's men, Elina's newfound freedom hardens into a singular purpose-revenge. 

The perfect trap presents itself at Scarcliffe Towers, where a fashionable shooting party of London's glittering elite will surely draw the criminal of the roads. There, amid polished smiles and dangerous flirtations, Elina encounters Ashby Harcourt-a scandalous Portuguese libertine known for his beauty, his charm, and his past association with her late husband. To Elina, he is a whoring cad; to Society, he is an indulgent rake. But beneath his cultivated indolence lies a web of secrets that could shatter Elina's new life. 

As Elina draws closer to the truth, the line between hunter and hunted blurs. What she uncovers forces her to confront not only the man behind the mask, but the realization that vengeance may demand a price she never expected to pay.
