A powerful book about escaping from a country, relationships and how people change over time, adjusting to new places and people....with a touch of "magic" or science fiction. "Doors" can help people escape from one country to another. So many people have escaped that the places they land have changed socially too, with locals reacting negatively or fleeing the area. IN the end one country comes up with a novel solution. The main story follows the two protagonists and they meet, decide to escape together, and the experiences they go through in each place. It is a powerful, beautifully written book.
