 ...St. Mungo's Homeless Charity
Although I have no personal experience of homelessness, I've always found it easy to imagine the way in which life might unravel through ill fortune or dire circumstances, leading to an existence on the street. After deciding that 10% of the royalties from my novels should go to charity, I discovered St. Mungo's. Based in London, it runs hostels and provides a range of services, including a creative writing group I attended, intended to help people get back on their feet. I feel very privileged to be in a position to help support this precious provision of a second chance. Mungos.org
