Sam has been haunted for years by the Sigil. She's drawn the pattern since she was a child, she has a tattoo of it, she sells prints of it. Then one day, she sees it on a statue in the window of Bilis Manger's shop.

It turns out the Sigil is very old indeed. Why has it been haunting her? Why is it on a Celtic statue of a bird? Where did it come from? Has a terrible entity been released from it's ancient slumber?
