Dashing Irish laird, Brendan O'Conor, pilots the powerful Formula One racing boat that is entered in the international competition to be held in Dublin, Ireland. Alyson McGrath, owner of a Napa Valley California vineyard, is sponsoring the American entry, the Magnum Red. When Alyson's ex-fiancé suffers brain-damage in a boating accident, she decides she hates the extremely dangerous sport. But when she meets the irresistible laird, she discovers the flames of love cannot be denied. By race day, their love is tested, not only by opposing viewpoints and thousands of miles of land and sea, but by the unexpected threat from the sociopathic killer who is prepared to commit murder to possess Alyson as his very own.
