Wonder Woman by Walter Simonson & Jerry Ordway

"Stricken with amnesia and stripped of her costume and super powers, Diana wanders the streets of New York unaware that she is in fact an Amazon warrior. With a little help from an ardent Wonder Woman fan, Diana needs to put the pieces of her life together in time to stop the Shattered God-a cosmic entity with the power to warp reality to his evil will. One way or another, Diana must figure out her past to save the future. Collects Wonder Woman #189-194."
