Sixteen-year-old Sofie is a dreamer, an artist and a romantic. So when she goes on exchange to Paris, she is expecting magnificent adventures of the heart and mind. Yet France isn't what she imagined. It's cold and grey, and speaking another language is exhausting. Sofie's more homesick than lovesick.

But then her host sister, Delphine, and fellow artist Olivier show her a different side of Paris, and Sofie starts to question her ideas of art, beauty and meaning. Of everything. There's truth in what her best friend, Crow, has been saying all along- the world is in crisis and people need to take notice. And when a catastrophe strikes close to home, Sofie realises she needs to act.

But what can one girl do? Will Sofie be able to find the courage to fight for change?

This One is Ours is a call to action for anyone who feels helpless about the state of society, as well as an ode to all the tiny beautifuls that make our world worth saving.
