New York Magazine/Vogue journalist Jon Gluck was living the dream at 38 - married, loving his first New York apartment and enjoying his baby daughter.  But, after a minor, innocuous slip on a patch of ice, he was devastated to be diagnosed with a rare, incurable blood cancer and given just 18 months to 3 years to live.  22 years on and counting, Jon has written a searingly honest account of his survival. 'An Exercise in Uncertainty – A Memoir of Illness and Hope’ documents how he’s beaten the odds and, more broadly, offers some gems on how to cope with uncertainly of any kind.
