The Field Trip — R.T. Martin

On a flight back home from her school choir trip, Kayla's airplane makes a sudden landing in a small airport. Only then does everyone find out this mysterious landing was because of the alien lights appearing in the sky. When the aliens attack Earth, Kayla and her friends are stuck in the airport with no electricity and no way to reach their families. They'll have to decide whether to wait around for help or risk trying to get home on their own.
