<I>Griffin?Foolish man. You cannot turn me into a phantom because you are frightened. You do not dismiss a muse at a whim. If you will not join me, then I will come to you. ?Sabine</I> <P>Sabine was supposed to be imaginary, a friend and lover that Griffin had created to soothe his loneliness. But she threatens to become embodied, to appear on his doorstep, in fact. So he runs.<P><I>Griffin & Sabine, </I>the most creative and talked-about bestseller of 1991, left readers on the edge of a precipice. With <I>Sabine's Notebook,</I> they begin?along with Griffin?the fall. Once again, the story is told through strangely beautiful postcards and richly decorated letters that must actually be pulled from their envelopes to be read. But this volume is also a sketchbook and diary kept by the possibly unreal Sabine, who is living in Griffin's house in London while he wanders through Europe, North Africa, and Asia, backwards through layers of ancient civilizations?and of himself.<P>Filled with her delicately macabre drawings and notations, the notebook adds a darker element of visual intrigue to their complex and mysterious world. For the thousands who finished <I>Griffin & Sabine</I> and asked, "What happened next?," this second volume in the trilogy provides the answers?but raises new and even more haunting questions of its own.
