Agnes, Hattie and Jake travel on the school bus together, but don't know each other well.

They plan a week in Weston, as a 'study break' before exams, but none of them admit the real reasons they need to get away.

Agnes must find her sister. Hattie can't bear being home now all her friends have ghosted her. And Jake is afraid he's ill and has absolutely no idea how to tell anyone.

In one amazing week, they'll risk their lives, face their fears and find themselves.
