for Now by Morris Gleitzman
Set in the current day, this is the final book in the series that began with Once, continued with Then and is . . . Now.
Felix is a grandfather. He has achieved much in his life and is widely admired in the community. He has mostly buried the painful memories of his childhood, but they resurface when his granddaughter Zelda comes to stay with him. Together they face a cataclysmic event armed only with their with gusto and love—an event that helps them achieve salvation from the past, but also brings the possibility of destruction.
