The Shape Of Sound

The Shape of Sound is a literary family novel told through the alternating lives of two siblings, Sono and Sora, ten years after the collapse of their parents' marriage.

Sono, nineteen, is already deeply embedded in music through solo work, a school band, and a university course. Disciplined, self-aware, and physically structured through the gym, he is determined to pursue music seriously without repeating the instability he saw in the adults before him. Sora, fifteen, sings instinctively, has a natural ear for piano, loves animals, and works with short videos shaped by sound, atmosphere, and emotional truth. Where Sono builds himself through control, Sora understands the world through listening.

As they move between London and regular visits to Japan and hold onto warmer, rarer memories of Portugal, the siblings begin to understand that what they inherited from their parents is larger than divorce. They inherit music, silence, discipline, sensitivity, cultural doubleness, and two competing ways of living: one built on faith, the other on safety. As Sono's life in music deepens and Sora begins finding her own artistic voice, both must decide how to carry the past without being defined by it.

Tender, intelligent, and emotionally precise, The Shape of Sound is a novel about siblings, art, family after fracture, and the quiet ways children turn inheritance into form.

A Letter to Okasan and The Shape of Sound belong to the same family story told across two generations.

The first follows Claudio, a Portuguese artist in London, as he writes to his former Japanese mother-in-law ten years after the collapse of his marriage to Akira. In revisiting their life across London, Japan, and Portugal, he tells the story of a family shaped by love, migration, silence, artistic longing, and the slow failure of a marriage that once felt unbreakable.

The second turns to the children of that marriage, Sono and Sora. Now older, they are no longer defined by the divorce itself, but by what it left in them: discipline, sensitivity, music, emotional intelligence, and two very different ways of hearing the world. As they grow into themselves between London and Japan, they begin to transform inherited pain into voice, sound, and art.

Together, the books tell one larger story: not only how a marriage ends, but how its children carry forward what was broken, what was beautiful, and what still remains.
