At just twenty-two, on the cusp of adult life, Suleika Jaouad was diagnosed with leukemia and given a 35 per cent chance of survival. For the next five years, her world comprised four white walls, a hospital bed, fluorescent lights, tubes and wires. She became patient 5624. At twenty-seven, and celebrating her first year of remission, Suleika realized that, having survived, she now had no idea how to live. And so she set out to meet some of the many strangers who had written to her about their experiences of life, death, healing and recovery in response to her Emmy-Award winning New York Times column, 'Life Interrupted'. Between Two Kingdoms is the result. Drawing on Suleika's TED Talk, now with 4 million views, it illuminates universal questions about how we live, mourn, heal and grow up, and what it means to begin again.
