A Mountain in my Heart provides an extraordinary insight into a teenage girl's journey on being unexpectedly diagnosed, with an exceptionally rare cancer. From the Welsh Mountains the author diarises the pre- and post-diagnosis of a cardiac sarcoma, alongside providing extensive research and insight which will help educate and support both Medical Professionals and families with children undergoing treatment. From walking up the mountains as part of her Duke of Edinburgh expedition award, the author progresses through her journey as she navigates hospitals across the UK whilst undergoing the effects of major open-heart surgery, chemotherapy, radiation treatment and everything in between. The author portrays a remarkable resilience of human spirit and writes with humour and honesty. There is currently no other book written by a young person that provides such an in depth, open and true reflection of a cancer diagnosis and journey. The author had foresight and fortitude to fill this gap with the intent to help others and raise money for charities. This is a truly remarkable testament and legacy.
