A modern miracle builds conflict between sceptics and believers, but will divine power be harnessed for good or evil?

Now a major film called The Unholy starring The Walking Dead's Jeffrey Dean Morgan.

In James Herbert's horror novel Shrine, innocence and evil have become one .

A little girl called Alice. A deaf-mute. A vision. A lady in shimmering white who says she is the immaculate conception. And Alice can suddenly hear and speak, and she can perform miracles.

Soon the site of the visitation, beneath an ancient oak tree, has become a shrine, a holy place for thousands of pilgrims. But Alice is no longer the guileless child overwhelmed by her new saintliness.

She has become the agent of something corrupt, a vile force that is centuries old.
