It isn't paranoia if it's really happening . . .

Anna Fox lives alone--a recluse in her New York City home, unable to venture outside. She spends her days drinking wine (maybe too much), watching old movies, recalling happier times . . . and spying on her neighbors.

Then the Russells move into the house across the way: a father, a mother, their teenage son. The perfect family. But when Anna, gazing out her window one night, sees something she shouldn't, her world begins to crumble--and its shocking secrets are laid bare.

What is real? What is imagined? Who is in danger? Who is in control? In this diabolically gripping thriller, no one--and nothing--is what it seems.
