A haunting family memoir about what we owe our ancestors and our descendants, from an unforgettable new voice

'Part of me knew what the hungry ghosts wanted all along, what they still want. It is not vengeance. No, they want something else, but we refuse to listen. They want us to face up to our broken obligations.'

Every spring during the Qingming Festival, people return to their home villages in China to sweep the tombs of their ancestors, making offerings of food and incense to prevent them from becoming hungry ghosts that could cause misfortune. Yet for the past century, a time ruptured by war and revolution, many tombs have been left unattended. Following a record year of wildfires, Alice Mah returns to her family's rice village in South China, and discovers that her ancestors are almost forgotten, and there are no tombs left to sweep. Instead, there are incalculable clan debts to be paid.

Here Mah chronicles her journey from the rice villages of South China to her home in post-industrial England, through the Chinatowns of Western Canada where she grew up, to the isles and industry of Scotland where she now lives. As years pass and fires rage on, she becomes increasingly troubled by her ancestors' neglected graves. Her research on pollution gives way to growing eco-anxiety, culminating in a crisis of spiritual belief.
