Hot As Fire — Virginia Henley

Hot As Fire is a far more fitting title than the original "Christmas Eve" for this anthology-length story.
Real estate agent Eve Barlow, a devout feminist, finds Clint Kelly, a macho firefighter, irritating beyond belief. When they become snowbound at a property on Lake Michigan, hot sparks fly between these complete opposits. But when Eve suffers a life-threatening accident, she discovers just how desirable it is to have a real man fill all her needs and teach her what it feels like when burning passion turns to love.
