Summary: Otto and Ana are kids when they meet each other. Their names are palindromes. They meet by chance, people are related by chance. A story of circular lives, with circular names, and a circular place (Círculo polar) where the day never ends in the midnight sun. There are things that never end, and Love is one of them.
