The premise is von Daniken-esque, ridiculous; star-gods bootstrapping hapless Sumerian humans until one of the gods is trapped in an ancient statue. The characters are expectable, even stereotypical. The bad guy is, literally, Satan (or Sadin).
And I enjoyed every word of The Goddess of Sumer, from the dream-sequence beginning to the happy-ever-after ending. Even while my inner voice kept saying you know what happens next, I had to keep reading. And that's the power of good story-telling, you care what happens to the characters. You don't have to believe—it is fiction, after all. A good tale-spinner makes you want to know how it all turns out.
Jenna Smith's tale opens on a nightmare. Jessica is being drawn to a glowing green female figure, even as she is chased by a growling beast. In her dream, she trips and hurts her ankle; when she wakes, her ankle is swollen. That's our clue that her dream is something more than REM sleep.
When Jessica learns that her beloved uncle Derek has been hospitalized, she rushes home to be with him, despite the presence of an old flame, Randy, on her uncle's ranch. Her uncle manages to tell her that there is an important box in the attic, and Jessica finds it contains a glowing green head from a woman's statue.
Her uncle's young friend Lance explains that the head is from a statue in which Sadin entrapped a Sumerian goddess, called Tiamat by some people, Horus by others. Lance has been chosen to be the next Guardian of the head, but Jessica's uncle Derek has been Guardian for decades. Sadin's powers, shattered by the goddess even as he trapped her in the stone, have had thousands of years to recover, Lance tells her. What's more, the evil-doers have located the latest Guardian, poisoning Derek in their attempt to reach the goddess-head.
