Three courses. Seven guests. One evening they'll never forget. Seven strangers meet at Serendipity's for an anonymously hosted dinner party. As the evening reaches its close, small black envelopes are placed in front of the diners... revealing the age at which each will die. Spooked, but not wholly shaken, the group disperses into the rainy night with the hope of forgetting the ghoulish stunt. But two weeks later, one dinner guest dies at the age foretold. Was it a tragic accident? Or something more sinister? As the years go by, the other guests begin to die in line with the predictions given on that first night. And it's up to the remaining few to figure who, if anyone, was behind that dinner party before their numbers catch up with them too. Told from the perspectives of the seven guests, Number's Up balances mystery and mortality perfectly, begging the question: how would you live your life if you know your number was up?
