Haley Finn might seem like any other teenager. Except that a curse on her mother 17 years ago left Haley with multiple personalities and some very inhuman abilities. Haley can manipulate the weather around her at will and her other personalities-JJ and Sara-each have unique abilities of their own. Too bad they can't agree on boys, hair styles, vices, or anything else for that matter. In fact, the only thing they have in common is a shared body and a mutual respect. Sometimes. One summer night after Haley puts on a wicked lightning display, weird things begin happening around town. Creatures unlike any they've ever seen appear out of nowhere. And one night one of them speaks to Sara-the personality with the ability to communicate with animals. Baudelaire tells Sara that the Lightning Riders have come for a boy who holds the answer to their freedom. Turns out longtime friend and boy next door (and crush of Haley's) Drew, might have some secrets of his own. It's up to Haley to get the girls to work together, because it's the only way to defeat the creatures' master and send them back to where they came from. And just maybe win Drew's heart in the process.
