Drakuun: Rise of the Dragon Princess #4 (1997)

She bested him in battle -- defeated him in a swordfight -- and that should have sent him packing. But he's Dard, the hotheaded, hard-drinking, womanizing commander of the Royal Border Patrol; and she's Karula, the beautiful, buxom, sword-wielding princess of Ledomiam. And so the battle in the bar has become a war of the sexes -- and the next battleground is Karula's shower! Grab a towel and shed your shirt, 'cause it's about to get hot and steamy!
