Owen believes he is chosen for a higher purpose, interpreting every event, even tragic ones, as God's signs and his predetermined path. This unwavering conviction raises questions about free will and predestination.

The unusual friendship between John, the uncertain doubter, and Owen, the small boy with the loud voice and unshakeable faith, forms the emotional backbone of the novel. Their relationship is built on mutual admiration and unconditional support.

Set during the turbulent 1960s in the USA, the novel captures social tensions and criticism of American politics by connecting Owen's story with the political events of the time, including the Vietnam War.
