Beth and Alice are twins whose musical journeys have taken them in separate directions, and who now long to work together again - the search for harmony and the challenge of unison underpin the novel. Learning to pitch their voices in a noisy world, the sisters hit keynotes for today - why you should be careful what you say, and why you should say what you think, how to mess up, and how to apologise - while a wide range of characters from different cultural tribes stumble around in search of what connects them.

Set in Liverpool in the months leading up to lockdown, a joyous, thoughtful story which celebrates the author’s passion for choral music-making.
