Selena's heading back to the silver screen! The superstar is going to be starring in an adaptation of the book The Sky is Everywhere.

The book is kwa Jandy Nelson, and is about a 17-year-old called Lennie Walker who's a typical "nerd" - she loves reading, plays in the school band, and is always upstaged kwa her older sis Bailey.

But things get complicated for Lennie when Bailey dies suddenly. Bailey's boyfriend Toby looks to Lennie for help, and so does a new cute guy Joe. Lennie has to deal with the loss of her sis, plus an unexpected upendo life.

Sel's going to play Lennie. Who would be a good actress to play her older sister? Does this sound like a movie you'd see?
