In The Petty Details for So-and-so's Life, Camilla Gibb tells the unusual story of two siblings, Emma and Blue, who, despite an almost telepathic connection, respond to the disruptions of their childhood and the sudden disappearance of their explosive father in remarkably different ways.

In her father's absence, Emma travels vast distances, both internal and external, in pursuit of a new family, and discovers a sense of belonging in the most unexpected of places. While Blue, her burly, tattoo-stamped brother, haunted by the brutal, criticizing voice of their father, sets off on a cross-country search for their elusive parent. In the novel's powerful conclusion, brother and sister find value in each other's quest, reconciled to the fact that one can love without ever truly understanding the other.
