In a quiet lakeside town in the North of England, an anonymous gunman enters a school. Hours later, Marty's mother Ava is dead, her arms outstretched to protect the children she taught.
As the town strives to regain its sense of community in the wake of tragedy, cracks emerge, and with them, conspiracies. Who is the shadowy figure chasing Marty as she grapples with her grief? And what of the group of people who insist the shooting never happened?
Together with her childhood friend Leo, Marty must piece together the mystery of that fateful day - and face up to the truth about the part she played.
Day One is a tender, heartbreaking novel about community, tragedy, and the lasting power of love from the bestselling author of Girl A.
