Lost Cause — Douglas Pratt

In Lost Cause, treasure hunter Rikki Talens returns, diving into the dangerous waters of the Gulf of Mexico on a quest to uncover the long-lost secrets of a Confederate blockade runner. What begins as a pursuit of riches quickly turns into a perilous journey, as Rikki battles treacherous currents, hidden traps, and rival treasure hunters with unknown motives. But the greatest threat lies in the shadows—an elusive figure whose true identity and intentions remain shrouded in mystery. As Rikki races against time to unlock the shipwreck's secrets, she discovers that some relics of the past are best left undisturbed.
