Jewish-American author Nathan Thrall hoped his new book, A Day in the Life of Abed Salama, would give the world an insight into the daily lives of Palestinians and Israelis — and perhaps start conversations about ending the cycle of violence. But when the Israel-Hamas war broke out just days after its publication, his book tour events were cancelled or postponed. Thrall talks to Matt Galloway about what can and can't be said in the heat of war, and the complicated road to peace.
