Our Missing Hearts

Celeste Ng, Abacus, £20

We find 12-year-old Bird, who hasn’t seen his Chinese-American poet mother for three years.

They were separated when the fictional US introduced a law allowing the removal of children of suspected dissidents, especially of Asian descent.

But then Bird gets an message from his mum and sets out to find her.

This tale of unbreakable love is haunting.
