Justina Wamae, has a book that she cherishes - Margaret Thatcher's autobiography. When she bought it in 2013, it cost a then princely sum of Sh3,500, which might as well have been her life savings because she was unemployed and had struggled to find a job at the time.
"It was money that my aunt had given me for a small job I had done for her. I think she gave me Sh5,000. That book! In fact, I don't like Wambui (her three-year-old daughter) touching it so that she doesn't tear it. I treasure it. I always go back to see what she used to say," she says.
