British Fantasy Society Best Novel (nominee)
Richard Young's planned relaxing week with his wife and kids is shattered when his nightmare begins with an insistent pounding at his door. The stranger begging to be let in is being hunted--not by a man or animal, but by something that cannot be seen or heard. It is a relentless, pounding force that has existed for centuries and is now unleashed to terrify, to ravage, and to kill.
