Ekahi, which means "one" in Hawaiian, is the first book in a romantic mystery series from Georgette Livingston that features the adventures of Holly St. James, private detective. In this first outing, Holly is annoyed that her brother Jack has given her yet another ho-hum assignment at their family's detective agency. This time she's supposed to be following a philandering husband. The husband, though, turns out to be loaded with charm and charisma, and Holly is dismayed to find herself attracted to him in a most unprofessional way.

When someone starts shooting at them both, Holly realized that the man she is following is no ordinary soon-to-be-divorced husband, and the case she is working on is no ordinary run-of-the-mill job.

Before the story ends, Holly will face duplicity and danger that are heart-stopping in more ways than one....
