Max Bellmore changes the style of narration when the two meet because the fragrance of love can be felt from a distance. Both of them were in search of the Pandora Box and this common quest brings them closer emotionally and physically. Accidental love separates the story from The Warlord and The Darkest Night, also the love in this story is innocent in comparison to the other two books that are mentioned.
The two lovers were not looking for each other, however, when they meet neither of them was strong enough to resist the temptation. The writer does not change the novel into a love story after that thus the main theme does remain the same.
