Do you believe everything happens for a reason? Liberty Sanderson did until the day she was diagnosed with cancer. Emotions she never thought she'd feel, guilt of being a burden on her family, fear of what lies ahead and optimism that she is strong enough to fight this, after all she has the support of her family and more importantly her twin sister Callie. In the midst of her gruelling chemotherapy treatment, Liberty begins to resent the sister who used to mean so much. Each time she sees Callie, she is reminded of how she used to look, the brightness she used to possess and the beauty she feels she has lost. In the midst of her pain, Callie becomes a constant reminder of what Liberty may never be and their relationship falters.Determined to reach her sister in the midst of her despair, Callie makes a surprising decision to prove to her sister that she is not alone. Defying Gravity is a touching short story originally published in an anthology in Ireland which not only chronicles Liberty's fight with cancer but the struggles in coming to terms with the effect her treatment has on her appearance and the resentment it causes when she sees her twin sister. "I know for the first time what it feels like to be alone in this life. They say blood is thicker than water but I don't know- sometimes family blood can get very diluted."
