My Secret Affair with the Duke

In Regency London, orphan Elisa is bought by Duke Alexandre Belmonte to impersonate his half-sister, Estela, and marry Frederico Viana, freeing Alexandre from his forced engagement to the obsessive Beatriz Viana. A cold bargain becomes forbidden desire when the two fall in love, but everything grows complicated because of a secret execution order Alexandre prepared for Elisa. When Beatriz exposes Elisa's identity at the ball, Elisa flees, certain Alexandre will kill her. Cornered by Beatriz at gunpoint, Alexandre takes a bullet for Elisa and confesses that the order was never signed. They discover identical childhood scars, proving that fate brought them together long before the bargain.
