We meet at the family’s home in Valencia, about 40 miles north of Los Angeles. It is cosy and lived-in, with toys strewn across the floor. With Jani and Bodhi at school, the flat is peaceful. We sit down at the kitchen table and Michael and his wife, Susan, relate the story of their daughter. Susan, 43, a former radio and news reporter, is animated and full of energy. Michael, 37, who looks a little weary, is articulate and passionate. We are here to talk about Michael’s book, January First, a terrifying account of his battle to save his daughter, published in Britain next month. Before I know it, five hours have passed.
