The last time Katy saw Jude was on a school trip: Jude was attacked by a stranger, and Katy ran away. Twenty years later, Jude is back, and her reappearance coincides with a series of unsettling incidents: a stranger appears in the downstairs flat, Katy’s house is vandalised, her mother is mugged, and her home ransacked. Jude also seems to know an uncomfortable amount about Katy’s current life. As they are forced to revisit the same rocky waters of friendship and power that they inhabited when they were fifteen, Jude and Katy realize that, when it comes to memory, truth, and family, nothing is what it seems.
