CONTAGION- A Divergent Spinoff

Nowhere is safe.
There's been an outbreak in Chicago.
High fever.
Cough.
Headache.
No fatalities... yet.
It spreads through the air rapidly and microscopically.
There's no stopping an enemy you can't see.
It started in Amity.
Then to Erudite.
Then to Candor.
To Abnegation.
To Factionless.
The only safe faction is Dauntless.
Don't touch anyone.
Don't talk to anyone.
Protect yourself through isolation.
