Just Jack is an unbelievable story of a boy who played truant for almost one year and a girl who left school when she was 14 yrs old. Strangely it began as a love letter to my family, and a legacy for future family generations. However, somewhere along the way it became a compelling story of our shared life together, of our challenges during the pioneering edge of cardiac medicine and Echocardiography in Australia, and of our dramas and struggles while we concurrently developed a very successful thoroughbred horse stud with many successful racehorses. This book is a celebration of a remarkable and extraordinary man who lived a thousand lives in one.
