Locklan's Key

Locklan your average 17 year old as a pretty average life she goes to highschool with her best friend (Lynx) gets pretty average grades, hates physical activities unless its archery (okay maybe the archery part isn't very average) But like a I said mostly average until one day their father the one person other than Lynx who cares about her vanishes. At first she thinks that he maybe went on a work trip and forgot to leave a note but then she realizes he's part of a much more important game, a game that she, Lynx and 16 other people both get a suspicious invite to.
