On the island of La Palma, in the Canary Islands, the Cumbre Vieja volcano is Ian's only chance at redemption; his last chance to regain his self-respect. He sees the signs of a volcano coming awake-the off-gassing, the deformation, the pattern of small earthquakes-all signs of a volcano getting ready to blow. But with his history as a drunken failure, no one believes him.

Ian knows that if the La Palma volcano explodes into the Atlantic ocean, the volcanic displacement will start a massive wave-a tsunami-moving across the Atlantic Ocean. Within hours, the giant wave will arrive on America's shores. If Ian fails again, millions of Americans-including the woman he loves-will be swept away.

WaveForm, the latest science-thriller from Greg Dahl, is a story of compelling characters facing the uncontrollable forces of nature. WaveForm is a story about ordinary people-a family on vacation at the beach, a beach-town police officer, a Florida widow who loves her home near the shore-and WaveForm is also a story about public officials and their science advisors who put politics ahead of public safety. WaveForm is about a real volcano and a catastrophic eruption, but it is primarily a story about people, characters we know and care about, trying to survive an unimaginable disaster.
