Long Way Down discussion

My second book was called Long Way Down. The book starts with the character Will talking about the killing of his brother Shawn. They follow 3 different rules: Don't Snitch, Don't Cry, and Get Revenge. Will finds Shawn's gun and decides to get revenge for his death. On the elevator ride down his apartment building, will is met with ghosts. At the end of the ride, Shawn's ghost asks Will "You coming?". We never get to see if Will made the decision to get revenge for his brother or not. I liked this book because it was a short read and it was interesting how it all took place in the span of an elevator ride.
