Erin Shipley grew up on Keystone Lake before moving to Tulsa and becoming an associate attorney. Now, she’s back, representing a client who is concerned about the flooding and property values around the lake. Properties underwater are being bought and sold for pennies on the dollar by someone called T & H Realty. When her friend’s uncle, Jeff, dies mysteriously on the lake, Erin wonders if it has anything to do with the real estate scam and launches an investigation. The dam is old and zebra mussels are clogging it, not allowing enough water to flow out. If the dam breaks, it will flood downtown Tulsa and areas around it. But that’s not the only danger…whoever killed Jeff isn’t finished with their diabolical plan, and Erin and those she loves are at risk from more than just a dam break.
