When a masked group claiming to be warrior angels kidnaps Gia Rossi, she believes it's retaliation for her wealthy husband's shady dealings. Squired into a high-tech underground world by her strangely gentle captors and placed under the tutelage of Joachim, their handsome leader, she soon learns that among her lost childhood treasures is a medallion, which places the fate of the world in her hands. Gia's job is simple: locate the relic and lead the angels to it…and somehow, fight the forbidden attraction that fast develops between her and Joachim.

As commander of the angelic warriors, Joachim must protect Gia and, with her help, locate the sacred relics needed to conquer the demon Therides. But Joachim doesn't count on falling prey to sexual attraction when it comes to their beautiful, headstrong captive and soon another battle commences, one between consuming desire for his charge and a weighty sense of celestial duty. For if Joachim and Gia succumb to the fire smoldering between them, it could prove to be the end of both their worlds.

Yet danger makes forbidden passion all the sweeter...
