This is a novella-length ebook, not a full-length novel, but it is a good entry point for the series, The Emily Kane Adventures.
With the help of her "Granny," the great Shinto Goddess of the Sun, Amaterasu-omikami, Emily Kane had the strength to fight off the black-ops teams hunting her. But now she needs to find some relief from Granny, and to reconcile herself to the violence she had to unleash. She hopes to find spiritual renewal in the crowded pantheon of the Hindus and Buddhists of Nepal. But the spirit of violence is not far behind her.
