Ordeal of a Maiden

Lysandra is a seventeen year old girl. She goes to Greenville High, just like all the other girls in Greenville, but she is not like them. She's a maiden, looking for her element to complete the metamorphosis and become a nymph. The metamorphosis has to take place on her eighteenth birthday, if it won't take place Lysandra will face a certain death. She thinks she has plenty of time to find her element before that. But will she still be so sure about that after a human finds out about her? Sudden mysterious events raise a lot of questions for her. Did her mother really disappear? Or did she just leave? What is the power of the amulet her mother left behind? And why didn't she find her element yet? Is something wrong with her?
