boiling pointAs Chaitén sleeps…

Two microbiologists monitor the effects of global warming in the shadow of the long-dormant volcano.

A celebrity scientist and his film crew arrive at the caldera to capture Chaitén’s spectacular scenery for a television audience.

And a Nobel Prize-winning scientist sits in his apartment in Paris, monitoring data on fifty-six volcanoes around the world—waiting for the one sign that his diabolical plan is about to be put into motion.

Soon, their destinies will converge. For the Earth has become a pawn in the biggest gamble ever played with humanity’s future…

And Chaitén is about to blow.

BOILING POINT is available from Amazon, Barnes & Noble, iTunes and Kobo.


“Fans of the late Michael Crichton will enjoy Dionne’s exciting second ecothriller . . . Crisp writing keeps the pace fast, and the tight interweaving of story lines bodes well for this author’s future efforts.” — Publishers Weekly

“Dionne hits her stride with this heart-thumping, timely thriller, one that rings with surreal authenticity.  All of the right elements — action, suspense, secrets, conspiracies — meld together, the plot built skillfully, like a master craftsman, one layer at a time.  Put simply, it’s a non-stop delight of a read.” –  New York Times bestselling author Steve Berry

“K.L. Dionne’s second eco-thriller is the sequel to Freezing Point, a gripping novel chronicling the battle for control of Antarctica’s ice. Think Dan Brown, only with more substantial material and fewer repetitive plot devices. Boiling Point features an eccentric group of characters — including two microbiologists, a celebrity figure, and a Nobel-winning scientist intent on destroying the world — and, of course, a storyline that promises to keep readers on edge. Boiling Point’s quick pacing and rapid-fire writing will satisfy any Michael Crichton fan, as well as anyone wishing for an entertaining read with global warming at its core.” — Sierra Club blog “Green Life”
