Formula: Another HELL Ranger Thriller

When Formula One champion and covert agent Devlin Lucchesi and his HELL Ranger crew return to the Monte Carlo Grand Prix to win big, a rival racer is fatally poisoned at the finish line. Devlin and the HELL Rangers suspect tainted grappa. They investigate Aurora Vineyard, set atop a hotly contested aquifer in the Italian Dolomites.

Threatened by extreme water rights activists and cut-throat industry competitors, CEO Erika Aurora, industry-dubbed "the Bloodsucker," hires Devlin and his crew to hunt down her company's usurper. The cases intertwine. Devlin deduces that the Aurora siblings may be tangled in a bloody power grab. Things heat up fast when the killer begins targeting the estate's sibling owners one-by-one.

Soon it becomes clear that a thirst for control and revenge is quenched only with a poison formula derived from the vineyard's secret family recipe. The stakes soar when the formula's lethal reach extends to the thousands gathered at a Palio horse race in Siena, including Devlin's son, and to the world leaders of a global water summit in Verona. Devlin must risk everything to hunt down the killer in time to halt a poisonous calamity that threatens worldwide ramifications.
