Cross Everything is a heart-wrenching cancer memoir, a fascinating popular-science detective story, and a witty and at times darkly comical take on a disease that half of us will experience at some point in our lives. When Henry Scowcroft's fiancée Zarah was diagnosed with stage 4 bladder cancer in 2016, their world fell apart. An award-winning science writer for Cancer Research UK, Henry had spent 14 years at the coal-face of cancer research, but now the disease had infiltrated his personal life too. In Cross Everything--his first book--Henry uses this unique perspective to tell the story of Zarah's illness, how he tried in vain to use everything he'd learnt in his professional career to try to save her, and in doing so, how he realized that even a career writing about cancer daily isn't enough preparation for what comes next. Along the way, Cross Everything brings the reader up to speed with the latest understanding of cancer--a complex disease with a Darwinian capacity to outsmart its host.
