Rimmer's Way (Harlequin Romance #2098)

the long version

Della tried to shut out the disturbing effect Cal was having on her. "Might be better if you let yourself go occasionally" he said. "I'd kind of like to see what's behind that wall you've built up around yourself." Della gasped as she realized the implication of his words. So he did want to make love to her! Well, he was right about the wall. What's more, she'd go on building--so high no man could scale it. Especially not Cal Tarn!
