The River Lea

Lea's family lives by the river Lea, where Lea (who was named after the river) grew up. When Lea is 8, she almost drowns in the river, and her older brother Trevor saves her. She eventually gains water powers when she turns 18, which is now. She figures out that she got these powers from falling into the river. Now that she knows she has these powers, she is trying to figure out how to stop them from going haywire before she destroys everything she touches.
