Summer Outing

Tranquillity.

That is what Ken and Sylvia Duke expect on their vacation trip to Seattle.

What they have every right to expect.

But then...

In a single instant of time...

Ken sees something so horrible it almost makes him come apart.

But did he really see it? Or was it just a flashback to his war experiences?

He doesn't know.

Decides he must investigate.

That leads to various consequences.

For one, contact with a police official who once was Sylvia's White Knight...

For another, the Dukes are led further and further into a quagmire of inexplicable discoveries.

The mystery deepens to the extent they realize they are in over their heads.

Too late...

Now they must fight with everything they have to try to survive in an environment out of their worst nightmares.
