I needs help :(

I'm writing a story and I absolutly need a great title. It's about a hidden princess named Lexi who wants to discover her realm. She wants to find out her families history but she finds out the world is in danger because a cursed villan is letting out dark jewels into the world causing the realm and people to disappear. Lexi wants to sacerfice herself but she won't until her questions are answered. She goes on a quest to the secret underground castle, but it's very hard to find since it is very unknown to all of Magicx. Finding a lost family member on the way, they both find the scroll to their family's history but find out it has been possesed by the villian. They think they are apart of the dark side so Lexi now thinks that it's a good idea to go to the dark side because she thinks the evil jewels mightbe a good thing. Her brother tries to stop her but fails. Lexi leaves to the dark side to get possesed by the villian. She tries to kill her brother until her memories come back. She remembers her mom and dad but she doesn't remember what happened to them. She turns on the villian and goes into his castle to find her real family history scroll. Her brother tells her everything about their family but all of sudden disapears.



Well that's it.. I kinda gave out to MUCH info but hopefully you can give me a title suggestion.

(P.S. I guess you can say it's a contest.. whoever's title I like will get to be a character in the book! :D)
