Toni Dwiggins is a third-generation Californian who migrated from southern Cal to northern Cal. What she likes most about her state is that one can go from the ocean to the mountains in one day, with a lunch stop in the desert. She likes it so much she has chosen those settings for her forensic geology books. These stories feature a young woman and her father-figure mentor, who analyze earth evidence to solve crimes and crises--and in the process get entangled in outdoor adventure and thrills.
A mystery at sea plunges the geologists into deadly waters. Investigating a strange fishing accident off the California coast, they track it to an even stranger project. Someone with toxic skills is at work in this sea. If the lethal project is not ended, the outcome will be unstoppable.
