Imagine you hear a noise in a completely dark room. You think there very well might be a big crazy guy with a large knife ready to pounce right in front of you. Would you turn on the light?
That's the creepy tense feeling of Bird Box (2014). No crazy guy with a knife, but some strange abstract entities that cause people and animals that see them to go insane, kill others around them, and kill themselves.
This is the story of Malorie and her children as they try to find safety blindfolded and in a blindfolded world. Taking off the blindfold outside could mean madness and death. The book starts a few years into the ongoing horror then alternates flashbacks and current action.
