"When will the world end? With Foxworth, a massive comet, hurtling toward Earth, humanity now knows the exact date. Seventeen-year-old Simon wants to spend his last weeks with the people he cares about most, especially his goal-oriented swimmer ex-girlfriend, Tilda, who dumped him shortly after the news broke. Since Lucinda was diagnosed with cancer she has retreated into herself preparing for the inevitable. Suddenly facing down a death that makes her the same as everyone else, she longs to connect again but doesn't quite know where to start. Reaching out to her former best friend Tilda seems like a good first step. Then Tilda is found dead and accusations start circling that Simon is the killer. As the days tick down, Simon and Lucinda only want to know the truth, but the more they uncover about the final days of the girl they both cared for deeply, the clearer the things that really matter become."--
