In the crystal-clear springs of Crystal River, Florida, the water remembers everything. Wildlife officer Coral Johnson knows these waters better than anyone - the manatees, the hidden currents, the fragile limestone beneath it all. When a routine investigation uncovers illegal underwater technology buried deep in the springs, Coral finds herself pulled into a danger far greater than poaching or pollution. Enter Reef Adams, a marine conservationist with a past he's spent years trying to outrun. The technology threatening Crystal River is built on his early research - work he believed abandoned, never weaponized. But someone has been waiting, and testing the systems limits. As springs collapse, docks vanish, and the ground itself begins to fail, Coral and Reef race to stop a man who has learned how to turn water into leverage-and ecosystems into bargaining chips. With sharp-witted kayak tour guide business owner Marina Rodriguez and Reef's fiercely loyal friend Kai Nahoa at their side, the fight becomes personal, dangerous, and impossible to walk away from. Because in Crystal River, the water doesn't just sustain life. It can destroy it. Traces in the Water is a fast-paced mystery thriller with heart, humor, and rising romance-where love surfaces under pressure, secrets refuse to stay buried and the line between saving the environment and surviving it grows dangerously thin.
