In the summer of 1972, on the night of their high school graduation, nine friends make a solemn vow to meet in twenty years' time. For Willa Scott, her best friend, Angel, and her boyfriend, Caleb, the future is a canvas to be painted in bold strokes and bright colours. But the ensuing decades bring change and separation as Willa drifts away from Caleb and Angel. Almost twenty years later, a chance meeting with Patrick Mulhaven, the bad boy of Beacon High, reminds her of their long-ago vow. On a mission to track down their old group, Willa discovers that Angel's trail after high school is ice cold. Convinced that someone has killed - and will kill again - to keep Angel's whereabouts hidden forever, Willa begins a search that takes her back through the looking glass. As the idyllic friendships of her youth are revealed as a tangled web of deception, betrayal and life-shattering secrets, whom can Willa trust?
