In The Italian's Bed

Description for IN THE ITALIAN'S BED by Anne Mather:

It's actually Tess's younger sister whom Rafe is after -- and she's gone missing, too! Despite Rafe's arrogant accusal, Tess decides to help him locate the runaways.

The situation is difficult enough without the incredible sexual tension that's growing between them. But Rafe pushes Tess away. He cannot let himself be consumed by the intense desire that would surely follow....
