A Line Drawn in the Sand captures the determination of several African nations, including Botswana, Nigeria, Senegal, and Tanzania, in providing lifesaving antiretroviral therapies to their citizens. By emphasizing the dramatic results that investments in AIDS treatments in Africa can bring, the book provides lessons to nations about scaling up their own treatment responses, hope to individuals and communities confronted with the often devastating impact of AIDS, and inspiration to the international HIV/AIDS community.
