I get it, Suki, but I hope it comes back for you.
Lock Every Door by Riley Sager
Jules Larsen just lost her job and her boyfriend all in one day. Now, with no new jobs on the horizon and no funds for a new place of her own, staying on her friends couch may be the way it is for awhile.
But, an amazing opportunity falls into her lap! Be an apartment-sitter and stay at the Bartholomew apartment building in New York City, a landmark building very close to Central Park. And, since the building doesn't like to have empty apartments, she will be paid twelve thousand dollars to stay for 3 months till a permanent owner moves in. How could she say no?
The building is old and mysterious and full of quirky, notoriously private residents and Jules quickly learns something is not quite right.
Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness that most frightens us.
