The son between the two main characters in the novel seem very tenuous at the beginning of the novel, but they operate very subtly in history.
The structure of the novel also slice, with a history 'truncated' (no beginning, no end much more) that despite its focus on the two heroes, focuses more on an event in the history of the world of the novel, which, paradoxically we discover the links between Vosill and Dewar.
