It's hard to say just how much of Sunshine's audience has been absorbed since it has gone the route in reverse: the journal, that of Jacquelyn M. Helton on which it was based, was used for a television motion picture in 1973; Norma Klein's paperback version (Avon) has been in much demand, particularly among young people, since 1974. Her barely fictional use of Jacquelyn's tapes is very simple, very straight, and unavoidably affecting--no Love Story II. Actually Jacquelyn, here called Kate, had no use for that book-film, ""so unreal."" To get on with the all too mortal facts--at 18(apple) she was diagnosed as having a sarcoma of the bone which would unquestionably travel quickly to the lungs giving her a ""chance to be one-legged and dying."" Meantime there's the baby she loves (by David) and David's successor Sam whom she certainly loves more than he does her since he's always ducking out on the situation, and just about no one else except a mother who exists via one telephone call and an understanding doctor who accepts her decision--no more radiation, no more drugs. It's more Jacquelyn's words than Norma Klein's that count and substantiate the fact that ""Dying's Such a hassle."" But this time at least it's as it is, as it was.
