Jess Walker, middle child of a middle class family, has perfected the art of vanishing in plain sight. But when she arrives at a concrete university campus under flat, grey, East Anglian skies, her world flares with colour.

Drawn into a tightly-knit group of rule breakers - led by their maverick teacher, Lorna Clay - Jess begins to experiment with a new version of herself. But the dynamic between the friends begins to darken as they share secrets, lovers and finally a tragedy. Soon Jess is thrown up against the question she fears most: what is the true cost of an extraordinary life?
