Some Body Like Me by Lucy Lapinska

As the world falls apart around them, piece by piece, Abigail Fuller spends humanity's final days looking after her husband David. But that's not true, not really. Abigail isn't David's wife.

She's not even human. She's a replacement, built in the image of the real Abigail, who died sixteen years ago. And in three weeks, when the law changes, Abigail will no longer have to do anything David says.

She'll be free to go where she likes, do whatever she wants to do. But having never lived for herself, Abigail now faces profound questions about what she is, how she wants to live, and who she wants to love. Perhaps she should start with herself.

Tender, powerful and thought-provoking, Some Body Like Me explores the concept of AI, the boundaries of sexuality and the indefinable human capacity for love at the end of the world.
