Those Who Hold the Threads

Some old Greek myths and the computer age collide in twenty-first century America. Just before she turns fourteen, Jane Smith learns what has been kept from her since she was born: she is destined for something different, more ancient, and much stranger than the ordinary American life she has expected. And when she meets the boy who calls himself Adam Night, she guesses there may also be mortal danger.

Jane travels through time and space to meet her destiny, aided by gods, goddesses, computers and a snippy GPS.

Those Who Hold the Threads by Joyce Allen weaves several genres together into a wonderful new one, fantasy/techo-mythology/adventure, with a spirited girl as the heroine.
