Since the day Emerson Pressman and her mother were diagnosed as HIV positive, nothing has been the same. When her mother dies of AIDS, Emmy has to go live with the father and stepmother she barely knows, and she feels more alone than ever. Now she has to take pills by herself, and there is no one left who understands what it's like to be afraid every time she has a cold. But when her father decides to send her to Camp Positive, a camp for HIV-positive children, Emmy begins to realize that she's not alone after all, and that sometimes, opening up to other people can make all the difference in the world.
