Adriana Herrera makes her historical romance genre debut with “A Caribbean Heiress in Paris.” This story takes place in 1889 during the Exposition Universelle in Paris and turns around the unstable Costa Rican rum heiress stars Luz Alana Heith-Benzan. Pragmatically, she consents to marry a Scottish duke. This is a fascinating story with well-developed characters, gorgeous landscapes, and the allure of the West Indies.
