Read the hilarious coming-of-age classic! Now a major film starring Rachel McAdams (Mean Girls, The Notebook) and Abby Ryder Fortson (Ant-Man).

Meet Margaret. She's going through all the same things most teenage girls have to face; fitting in, friendship and first bras.

Life isn't easy for Margaret. She's moved away from her childhood home, she's starting a new school, finding new friends – and she's convinced she's not normal.

For a start she hasn't got a clue whether she wants to be Jewish like her father or Christian like her mother. Everyone else seems really sure of who they are.

And, worst of all, she's a 'late developer'. She just knows that all her friends are going to need a bra before she does. It's too embarrassing to talk to her parents about these things.

So she talks to God instead – and waits for an answer . . .
