Galatea

From publisher blurb:

Being programmed to hide the truth, even from yourself, about your true nature is very harmful when you have no memory of your past and no identity. "Jane Cyprus" knew she was different. The more she worked to give back to the community that aided her, the more she discovered about just how different she was until she eventually took up a fancy uniform and code name and joined the ranks of the city's heroes. While Jane believes she's living up to her true calling as GALATEA, the secret of her past may never come to light. Her subconscious self will see to it.
