The Servants of Twilight:

To his mother, Joey seems an ordinary six-year-old boy - special to her, but to no one else. To the Servants of Twilight, however, he is an evil presence who must be destroyed - an Anti-Christ who must die.

The terrifying ordeal for Joey and his mother begins in the supermarket car park where an old woman accosts them and pursues them with her terrible threats. Christine's world is turned into a nightmare of terror. Only her love for her child, and the support of the one man who believes her, gives her the chance to survive the Servants of Twilight...

Darkfall:

They found four corpses in four days. Each more hideously disfigured than the last, the bodies punctured with dozens of tiny wounds.At first they thought it was a savage psychopath. Then they thought it was a vicious gangland war. Then they thought packs of demonic rats were escaping through the ventilation system.

Then they saw the nightmare itself, in all its mottled, slimy horror, coming after them from every direction, and they realized that the Gates of Hell had been left open...

Phantoms:

They found the town silent, apparently abandoned. Then they found the first body, strangely swollen and still warm. One hundred fifty were dead, 350 missing. But the terror had only begun in the tiny mountain town of Snowfield, California.

At first they thought it was the work of a maniac. Or terrorists. Or toxic contamination. Or a bizarre new disease.

But then they found the truth. And they saw it in the flesh. And it was worse than anything any of them had ever imagined...
