The new thrilling instalment of John Connolly's popular Charlie Parker series. He is our best hope. He is our last hope. On a lonely moor in the northeast of England, the body of a young woman is discovered near the site of a vanished church. In the south, a girl lies buried beneath a Saxon mound. To the southeast, the ruins of a priory hide a human skull. Each is a sacrifice, a summons. And something in the shadows has heard the call. But another is coming: Parker the hunter, the avenger. Parker's mission takes him from Maine to the deserts of the Mexican border; from the canals of Amsterdam to the streets of London - he will track those who would cast this world into darkness. Parker fears no evil. But evil fears him . . .
