Madeleine McCann’s parents are marking her 8th birthday Thursday with a new book and renewed vows that their missing daughter will not be forgotten.
In the book, simply called Madeleine, Kate McCann describes the moment she entered the British family’s rental apartment in Praia de Luz, Portugal, at 10 p.m. on May 3, 2007, and realized Madeleine’s bed was empty.
Seeing the windows open, Kate writes that she felt “nausea, terror, disbelief, fear. Icy fear,” and said to herself: “Dear God, no! Please, no!”
