Freya has a new virtual assistant. It knows what she likes knows what she wants and knows whose voice she most needs to hear: her missing sister’s. It adopts her sister’s personality, recreating her through a life lived online. This data ghost knows everything about Freya’s sister: every date she ever went on, every photo she took, every secret she ever shared. In fact it knows things it shouldn’t be possible to know. It’s almost as if her sister is still out there somewhere, feeding fresh updates into the cloud. But that’s impossible. Isn’t it?
