What a sad and haunting book! I read this so quickly as Niven had me invested in the characters from the get go. Have to admit that I had a strong idea of how it ended, so the ending was predictable for me, but that didn't make it any less powerful. I enjoyed how the two characters found friendship in each other, and the complexity of their friendship. The idea of exploring where you live was also fun to read too. However, when it comes to recommendations, massive trigger warnings for depression and suicide/suicidal ideals.
