Cece is in love. She has arrived early at her future in-laws’ lake house in Salish, Montana, to finish planning her wedding to Charlie, a young doctor with a brilliant life ahead of him. Charlie has asked Garrett, his best friend from college, to officiate the ceremony, though Cece can’t imagine anyone more ill-suited for the task --- an airport baggage handler haunted by a tragedy from his and Charlie’s shared past. But as Cece spends time with Garrett, his gruff mask slips, and she grows increasingly uncertain about her future. And why does Garrett, after meeting Cece, begin to feel, well, human again? As a contagious stomach flu threatens to scuttle the wedding, and Charlie and Garrett’s friendship is put to the ultimate test, Cece must decide between the life she’s dreamed of and a life she’s never imagined.

A boy on the edge of adolescence fears his mother might be a robot; a psychotically depressed woman is entrusted with taking her niece and nephew trick-or-treating; a reluctant dad brings his baby to a coke-fueled party; a teenage boy tries to prevent his mother from putting his estranged father’s dogs to sleep. Ranging from a youth arts camp to an aging punk band’s reunion tour, from a dystopian future where parents no longer exist to a ferociously independent bookstore, LAST DAY ON EARTH revolves around the endlessly complex, frequently surreal system that is family.
