God on a Harley - Joan Brady.

This is a fictional account of one woman's journey of spiritual awakening. Nursing the heartbreak of numerous failed romances, Christine Moore is desperately seeking to bring meaning and happiness into her life when God, in the form of a cool biker who calls himself Joe, comes to help her find her way. As he leads her gently to the discovery of her "personal commandments" for living a joyous life, she grows through the self-imposed limitations she has adopted and learns how to truly love herself. And in doing so, she also learns how to truly love someone else.
