Fear of Falling [Treasure Planet Fanfic]

A long time ago a girl named Vanessa Kendrick disappeared from Jim Hawkins's 5th grade class. He vaguely knew her, so he didn't think too much of it until the same girl showed up on a pirate ship about to raid his. The crew of the R.L.S. Legacy was victorious and Vanessa was taken as an unexpected prisoner. She was allowed to stay on the ship as they journeyed to Treasure Planet, and over time Jim gets the quiet, shy girl to loosen up and live life.
