Here's a more detailed breakdown:

* The Journey: The book ends with Annemarie and Ellen, disguised as each other, arriving at the Swedish border. They are accompanied by the fishermen who helped them get there.

* The Escape: As they cross the border, they are met with warmth and kindness from the Swedish people. They are safe from the Nazis.

* The Ending: The book leaves the reader with a sense of relief and hope. Annemarie's courage and selflessness have saved Ellen's life, and she now has a chance to live a life free from fear.

While the ending focuses on Ellen's safe arrival, it also implies the enduring impact of the experience on Annemarie. She has experienced firsthand the horrors of the war and the importance of courage and kindness.

Remember, "Number the Stars" is a story of hope and resilience in the face of adversity.
