Bird Box by Josh Malerman

Malorie lives near Detroit with her two young children in an abandoned neighborhood. However, she has no idea what really lurks beyond her house because everyone has to wear blindfolds whenever they go out. Four years ago, people mysteriously began committing suicide after seeing some unknown creature. Back then, Malorie found a safe shelter with some other people, but now she and the children are on their own. Malorie decides to make a harrowing journey to what she believes is a safe haven, but to get there she must, along with the kids, row sightless for twenty miles down a river... Bird Box is a fast-paced story of fright, survival, and hope.
