A moving novel about learning to find happiness in the face of uncertainty and discovering a love that transcends the boundary between life and death. Seventeen-year-old Alex Byrd is about to have the worst day of her life, and the best. A routine blood test that will reveal her leukaemia has returned, but she also meets Jamie Orange. Some people believe in love at first sight, and some don’t. I believe in love in four days. I believe in falling. Both teenagers have big dreams, but also big obstacles to overcome. ‘Promise me you won’t try to die,’ I said. ‘Ever.’ ‘Promise me you won’t either,’ he countered. ‘It’s not really something I can control.’
