"I've skipped all other reading in favor of this enthralling world of loyalty, betrayal, and pyroclastic flows." (Amazon reviewer)

Mystery. Thrills. Adventure. The first three novels in the series:

QUICKSILVER: Forensic geologists Cassie Oldfield and Walter Shaws plunge into the dark history of the California gold country, into the dark past of two brothers, into a poisonous feud that threatens both lives and the land.

BADWATER: Death Valley earns its name when a terrorist threatens to unleash lethal radioactive material. The only ones who can stop him are the geologists, and they are up against more than pure human malice. The unstable atom--in the hands of an unstable man--is governed by Murphy's Law. Whatever can go wrong, will go wrong.

VOLCANO WATCH: The volcano beneath the geologists' hometown is seething, and the mayor is found murdered with a note saying NO WAY OUT. The fate of the town now rests in the hands of an emergency planner with his own twisted agenda. As the volcano moves toward red alert, the geologists race to prevent 'no way out' from becoming a prophecy.
