In Void If Detached , Mark Green gives us a clear look at the way a man in his forties approaches his diagnosis of a rare form of brain cancer called anaplastic ependymoma. His diagnosis was later revised to glioblastoma, of which he said, "I had a golf ball in my head, and I'm not even very good at golf." Through five surgeries, and thirty-three radiation treatments and three years of constant chemotherapy, Mark channeled his thoughts into the blog that he began after his initial diagnosis. You will laugh, cry, wonder, and revel in the writings put forth by this intrepid chronicler. Proceeds to benefit The Mark R. Green Trust and Accelerate Brain Cancer Cure (ABC2)
