Aphrodite's girdle is missing, and the magical artifact will take all of Hale's superpowers to retrieve. The woman who found the belt - one Tracy Tannin - wasn't exactly Ms. Popular before donning it. Now everyone wants her, including some very nasty bad guys.

Every hero has a different quest, and the more time Hale spends protecting her, the clearer it becomes that Tracy is a goddess worth devotion, no matter what she's wearing.
