a fight with luck and a meeting with fate

Mary weather had been living her life alone with her tree and maps for plenty of years. and she'd been a guardian through it all. but when a new and upcoming guardian starts to disrupt her routine she gets a little more then annoyed. then Mary's long time rival comes into play, and with Pitch Balck now out of the picture, she's ready for some fun. Mary is not. but it seemed inevitable because she knows her rival better then anyone. she's her sister after all. will Mary help the guardians? yes. will she do it willingly?....no. but she gets dragged along for an adventure she didn't ask for, and power that she'd treid to keep hidden. and a pesky boy keeps on making her blush. why was her life like this?
