When Henry Scowcroft's partner 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', 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 realised that even a career writing about cancer daily isn't enough preparation for what comes next. Along the way it brings the reader up to speed with the latest understanding of cancer - a complex disease with a Darwinian capacity to outsmart its host.
