Denton Little's Deathdate takes place in a world exactly like our own except that everyone knows the day on which they will die. For Denton, that's in just two days — the day of his senior prom.
Despite his early deathdate, Denton has always wanted to live a normal life, but his final days are filled with dramatic firsts. First hangover. First sex. First love triangle — as the first sex seems to have happened not with his adoring girlfriend, but with his best friend's hostile sister. (Though he's not totally sure — see, first hangover.) His anxiety builds when he discovers a strange purple rash making its way up his body. Is this what will kill him? And then a strange man shows up at his funeral, claiming to have known Denton's long-deceased mother, and warning him to beware of suspicious government characters... Suddenly Denton's life is filled with mysterious questions and precious little time to find the answers.
