No Safety in Number, book 3: No Dawn without Darkness
Dayna Lorentz2015

First–a bomb released a deadly flu virus and the entire mall was quarantined.

Next–the medical teams evacuated and the windows were boarded up just before the virus mutated.

Now–the power is out and the mall is thrown into darkness. Shay, Marco, Lexi, Ryan, and Ginger aren’t the same people they were two weeks ago. Just like the virus, they’ve had to change in order to survive. And not all for the better. When no one can see your face, you can be anyone you want to be, and, when the doors finally open, they may not like what they’ve become.

If you think it’s silly to be afraid of the dark, you’re wrong.
Very wrong.
