Clementine Darcy is floundering. She wants to be the kind of fish who swims to the swish of her own fins - upstream, not simply carried along by the current. But she is finding the swirling waters of school and home difficult to navigate: her friendship group is splintering, her brother Fergus won't leave his room, her sister's life is not as perfect as Clem thought...and then there's the New Boy, who is dapper and intriguing, but hiding secrets of his own. Clem is desperate for everyone - including herself - to be happy, but she discovers that her idea of helping doesn't always work as well as she imagined. Can Clem be the girl she wants to be? Will she learn to accept that there are things she can fix and things she cannot? Will she find a way to know the difference?
