Sixteen and Dying

You don't know me, but I know about you....
I can't make you live longer. I can't stop you  from hurting. But I can give you one wish, as  someone did for me.
It's hard for Anne Wingate  and her father to accept the doctors' diagnosis:  Anne is HIV positive. Seven years earlier, before  blood screening was required, Anne received a  transfusion to save her life, and the blood was  tainted. Now Anne must deal with the inevitable  progression of her condition. When an anonymous  benefactor promises to grant a single wish with no  strings attached, Anne decides to spend the summer on  a ranch out west and live as normally as she  possibly can. The summer seems even better than she  dreamed, especially after she meets Morgan. But  Anne hasn't confided in Morgan about her condition,  and when her health begins to deteriorate, she  suddenly leaves the ranch.
Is there time  for Anne and Morgan to meet again?
