This was was great. Sylv.ie is an artificial intelligence "Doll" designed to be a mistress to a rich man. In many respects it reminded me of Clara and The Sun, but I think explored a world of AIs more thoroughly and with more story. It develops lots of interesting feminist themes around sex/sex work, and women's roles/identities. Sylv.ie was a compelling narrator, moving from innocence to a bleak understanding of the reality of her life.
