Everyone who was invited to the house knows Walter--well, they know him a little, anyway. Some met him in childhood; some met him months ago. And Walter's always been a little... off. But after the hardest year of their lives, nobody was going to turn down Walter's invitation to an astonishingly beautiful house in the woods, overlooking an enormous sylvan lake. It's beautiful, it's opulent, it's private--so a week of putting up with Walter's weird little schemes and nicknames in exchange for the vacation of a lifetime? Why not? All of them were at that moment in their lives when they could feel themselves pulling away from their other friends; wouldn't a chance to reconnect be... nice? In The Nice House on the Lake, the overriding anxieties of the 21st century get a terrifying new face-and it might just be the face of the person you once trusted most.
