Francesca battles her mother, Mia, constantly over what's best for her. All Francesca wants is her old friends and her old school, but instead Mia sends her to St. Sebastian's, an all-boys' school that has just opened its doors to girls. Now Francesca's surrounded by hundreds of boys, with only a few other girls for company. All of them weirdos or worse.
Then one day, Mia is too depressed to get out of bed. One day turns into months, and as her family begins to fall apart, Francesca realises that without her mother's high spirits, she hardly knows who she is. But she doesn't yet realise that she's more like Mia than she thinks. With a little unlikely help from St. Sebastian's, she just might be able to save her family, her friends, and especially herself.
