‘My family tree is not simple; my lineage is not linear. There are the branches we see and the roots we do not. Not all bloodlines flow with blood.’

When Rebecca Coxon uploaded her genetic data to an ancestry website, she had no idea that it would start a chain reaction. The secrets revealed by her genes would alter Rebecca's understanding of identity and family forever … beginning with the shocking discovery that her father was not biologically related to her.

In this deeply honest and intimate memoir, Rebecca – a donor-conceived IVF triplet who has donated her eggs and undergone fertility treatment herself – shares her remarkable story. It’s one of family secrets, shame, resilience and warmth, offering a profound glimpse into the consequences of how we choose to create new life.

Written with nuance and tenderness, Inconceivable is both a beautiful meditation on our place within history and the wider universe, and a love letter to family in all its forms.
