Despite its unconventional structure, I really liked this story. It’s charming. The story consists of approximately 20 short brother-sister dialogues, spread across 20 years. Despite the appeal of symmetry, there’s no definitive explanation as to why they don’t see each other that often. I was expecting some kind of reveal at the end, but there was no exposition-drama-resolution arc here. What impresses me is the author’s ability to create a touching and compelling relationship using nothing but dialogue. That is unique. Typically, stories require some kind of conflict, crisis, and context to really be engaging, but this story felt like a stroll along a beach. My last criticism is an over-reliance on stereotypes, namely a tattooed, motorcycle-driving, leather-jacket-wearing (&tc) career criminal, and a “goody” college girl raised in a “goody” household. The one-dimensionality of the characters subtracts (though only very slightly) from the story. Other than that, I appreciate a refreshing read from a refreshing author.
