This book was sold to me as sci-fi but it's not as simple as that. Yes, there's a humanoid android and an experiment at the centre of this story but the specific context of grief changes the focus.

This book is about family dynamics, the value of memories, what makes a human human and what we need to thrive. 

I can't say much more without spoilers so I'll end with this: I've learned a few things about myself when I wasn't expecting to.
