Publisher's Synopsis
Newly divorced Jo is delighted to move into her best friend's spare room almost rent-free. The high-tech luxury Camden flat is managed by a meticulous tech tool, a Home Assistant called Electra, who takes care of the heating and the lights - sometimes Jo even turns to her for company. Then, late one night, Electra speaks one sentence that rips Jo's fragile world in two: I KNOW WHAT YOU DID. Jo is horrified, because in her past she DID do something terrible. Something unforgivable. Only two other people in the whole world know her secret. And they would never tell anyone. Would they? As a fierce winter brings London to a standstill, Jo begins to understand that the Assistant on the shelf doesn't just want to control her; it wants to destroy her...
