With the end of the world predicted, reality bends in an unexpectedly quirky and heartwarming novel about human connection and the meaning of life and death by the bestselling author of Sorry I Missed You. In the same week, Marlen and Hilda's family receives two significant pieces of news: One, Marlen has been diagnosed with a terminal illness. Two, a cosmic blast is set to render humanity extinct within a matter of months. It seems the coming Christmas on their Saskatchewan farm could be everyone's last. Preparing for the inevitable, they navigate the time they have left together. Marlen and Hilda channel their energy into improbably prophetic works of art. Hilda's elderly father receives a longed-for visitor from his past. Hilda's preteen nephew goes missing, and his mother refuses to believe the world is ending. All the while, Hilda's daughter struggles to find her way home from Berlin with the help of an oddly familiar stranger. For everyone, there's an unsettling feeling that this unprecedented reality is somehow something they all remember. As the planet holds its collective breath to see what happens next, the family--amid chaos, denial, acceptance, and hope--determines to live every moment as if it is their last. Because, well, it just might be.
