Louis Lasker loves his family dearly - apart from when he doesn't. There's a lot of history. His father's marriages, his mother's death; one brother in exile, another in denial; everything said, everything unsaid. And now his father (the best of men, the worst of men) has taken a decision which will affect them all and has asked his 3 sons to join him on one final journey across Europe. But Louis is far from sure that this trip is a good idea. His older half-brothers are wonderful, terrible, troublesome people. And they're as suspicious as they are supportive - because the truth is that they've never forgiven their father for the damaging secrets and corrosive lies of his past. So how much does Louis love his dad - to death? Or can this flawed family's bond prove powerful enough to keep a dying man alive?
