Diamond in the Snow — Diana Hunter

When a sudden snowstorm unexpectedly gives her the afternoon off from school, all Carolyn Brooks intends is a night at home grading papers. But when her car slides off the road, Paul Anderson -- the arrogant but gorgeous head of the English department -- rescues her. He takes her to his home, and Carolyn finds herself drawn to this modern knight.

But Paul is sure the petite schoolteacher is too delicate for his particular desires. He's not the White Knight she imagines…his tastes run much darker.
