Beneath the Surface

The one thing everyone gets wrong about diving.

When a rival dive-shop owner dies during a routine wreck dive on the USS Spiegel Grove, the official verdict is accidental drowning. Every detail checks out — the gear, the buddy system, the dive plan. Textbook, really. That's exactly what bothers Cass Mercer. In her thirty years of diving, she's never seen anyone do everything perfectly by accident. Cass runs Lower Depths Dive at the less-glamorous end of the Key Largo marina, and she knows the local dive community the way she knows the reefs — every current, every shadow, every thing that doesn't quite belong. The more she looks at what happened on the Spiegel Grove, the more she finds things that don't belong. Her ex-husband thinks she's projecting. Officer Reyes thinks she should leave it alone. Jonah Pike, her most reliable charter captain, thinks she's probably right. Cass has learned to trust the water. She's starting to trust her instincts about what happened beneath it.

The Second Plan

Some disappearances are meant to look like accidents.

A woman vanishes from the Keys under circumstances that don't add up, and Cass Mercer finds herself pulled into a case that isn't what it first appears to be. The Keys have a way of making things look simpler than they are — the water is clear, the sky is open, and there's nowhere obvious to hide. Which is why, when someone does manage to disappear here, it usually means they had help. Cass isn't a detective. She runs a dive shop, certifies recreational divers, and occasionally argues with the marina harbormaster about dock fees. But she's also someone who notices when the story doesn't match the dive log. And this story doesn't match.

About the Series

The Cass Mercer Mystery Series is set in Key Largo and the Florida Keys — a world of warm water, tight-knit dive communities, and the kind of small-town dynamics that make secrets both harder to keep and harder to find. Each book is a standalone mystery, though characters and relationships deepen across the series. The diving in these books is technically accurate because the author is a certified scuba instructor with over thirty years of experience. The fish are real. The wrecks are real. The murders are fictional.
