Are You Happy Now: 'One of the best novels of 2023' Sara Collins

At a New York City Wedding, on a sweltering summer night, four people are trying to get their lives started. Yun has everything he's ever wanted, but somehow it's never enough. Emory is finally making her mark, but feels the shame more than the success. Andrew just wants to be honest, but had lied to himself his whole life. Fin can't resist falling in love, but can't help wrecking it all either. Then the four of them watch as one of the guests sits down and never gets back up. Soon it's happening everywhere. Is it an illness or a choice? Because how can anyone be happy in a world where the only choice is to feel everything - or nothing at all?
