Chronicles of Reflection

The main character is a nameless girl with strange healing powers. She wakes up in the middle of a forest, unable to remember her name, past or how she arrived there. Her only belongings appear to be a blank book with a white gem embedded in its cover. From there, she begins to journey across the many islands of Reflection, meetings its inhabitants and seeking the truth behind her origins. What she encounters on the way will change not only her view of the world but reveal the truth about Reflection itself.
