At the end of season three, Angel left Sunnydale without looking back, and without saying good-bye to Buffy. This story takes up directly from the season finale, following Angel as he heads to L.A., and Buffy prepares for her life without him in Sunnydale. They earned a lot of enemies together, and now that they're apart, those forces are closing in. But the connection Buffy and Angel had was closer than anyone knew, and those who thought to take advantage of their separation are in for a surprise.
