Imagine being thirteen years old, and knowing, without the slightest shadow of a doubt, that you were conceived for a specific purpose.
Anna Fitzgerald was selected from several other embryos by her parents, Sara and Brian, because she was as close a genetic match as possible to her older sister, Kate. Kate was dying of cancer, and none of the treatments were working anymore. Anna was created to save her sister’s life.
Anna donated chord blood when she was born. Then she donated blood to Kate, several times, screaming as the doctors held her down. Anna had to take shots every day for a while so her body would produce an extra amount of the things that Kate’s body needed. Kate received Anna’s bone marrow more than once.
