Anxious People, Fredrik Backman

Looking at real estate isn't usually a life-or-death situation, but an apartment open house becomes just that when a failed bank robber bursts in and takes a group of eight strangers hostage. Each of them carries a lifetime of grievances, hurts, secrets, and passions that are ready to boil over. None of them is entirely who they appear to be. In short, they are the worst group of hostages in the world. But as teh minutes tick by, they begin to suspect that the criminal mastermind holding them hostage might be more in need of rescuing than they are. As the authorities and the media surround the premises these reluctant allies will reveal suprising truths about themselves and set in motion a chain of events so unexpected that even they can hardly explain what happens next.
