Thierry Bonnenfant has a mission to fulfill - transport a padlocked casket of holy relics across the sea to Normandy. Sounds easy enough, until he finds that his fellow travelers will be none other than a group of ...nuns.

Thierry was hoping for different company, something decidedly less virginal. Now, resolved to a very dull journey, where his only pleasure is arguing with a naughty, quarrelsome nun named Sister Vivienne, he has no warning of the storm ahead.

Vivienne is also on a mission. The priceless vase hidden inside that casket of relics is her pass to freedom. All she has to do is find the key in Bonnenfant's breeches. Apparently he's all brawn and no brains. Seducing him to get that key should be her easiest task ever.

But she's reckoned without this particular sinner's last remaining scruples. And the reckless, bloodthirsty warrior's only fear. Of nuns.
