Mary Rodgers was an accomplished author, screenwriter, and composer. She authored Freaky Friday, a book that has sold more than a million copies and has been made into two movies. Mary was the creator of two other novels for young readers, Summer Switch and A Billion for Boris, as well as the music for the musical Once Upon a Mattress. Mary Rodgers lived in New York City until her death in 2014.

Hadley is pretty much the model student: straight As, perfect attendance, front row in class. So what if she's overstressed and overscheduled: She's got school covered. (Life?not so much.)

Ms. Pitt is the kind of teacher who wants you to call her by her first name and puts all the chairs in a circle and tells her students to feel their book reports.

Hadley wishes Ms. Pitt would stick to her lesson plan. Ms. Pitt wishes Hadley would lighten up.

So when Hadley and Ms. Pitt find themselves switched into each other's bodies, the first thing they want to do is switch right back. It takes a family crisis, a baffled principal, and a (double) first kiss to help them figure out that change can be pretty enlightening.

Even if it is a little freaky!
