THE ENEMY IS INSIDE US.

The SymboGen-designed parasites were created to relieve humanity of disease and sickness. But the implants in the majority of the world's population began attacking their hosts, turning them into a ravenous horde.

Now those who do not appear to be afflicted are being gathered for quarantine as panic spreads, but Sal and her companions must discover how the parasites are taking over their hosts, what their eventual goal is and how they can be stopped.

How we calculate this

These are editorial estimates of intensity, informed by reading and review evidence, then checked before publication. They aren't star ratings, reader-vote averages or a measure of quality.

Each dimension runs from 1 (low) to 5 (exceptionally intense). A 5 is reserved for strongly consistent evidence. People experience horror differently.

Scary: Fear, tension and immediate threat.
Creepy: Unease, dread and an uncanny atmosphere.
Gore: Graphic injury, blood and bodily detail.
Disturbing: Upsetting ideas and lingering psychological impact.
Weird: Surreal, strange and reality-bending elements.

We draw a filled profile only when all five scores have been reviewed. Unrated does not mean mild. Missing scores are not estimated from genre tags or your saved taste. This profile isn't a complete content-warning guide.
