Esther, as the (current) world knows her, is an upright and kind individual. Due to her ability to heal, she is well-liked and admired among the citizens. Her younger sister Mytia, however, could not be more envious. During the evening of her engagement party, Esther catches Mytia secretly meeting with her fiancé Daniel. An infuriated Mytia lunges towards Esther, and the next moment, Esther discovers that her Ability has been stolen! As if thrust back into the events of the novel, Esther can no longer heal.
