What is the main conflict in Inside the Walls of Troy by Clemence McLaren?

"Inside the Walls of Troy" tells the story of the Trojan War and the events leading up to the war. The beginning of the story is told from Helen's perspective. It is Helen's decision to run away with Paris that starts the war. Helen’s great beauty makes her the jewel of Greece. However, since she is only twelve years old at the beginning of the book, she is more interested in horses and games than in her beauty or its implications.
