Into every life, a little rain must fall. For Sharra Marsden, high school dropout, member of the Calicos gang and estranged from her widowed mother, the rain's become a deluge until she receives a golden anklet.

In the adventures to follow, Sharra runs across unexpected allies and unpredictable enemies while trying to find her place in the world around her, with the climax a final battle to determine Earth's fate and hers.
