This is an incredibly well written book, and I'd recommend it to people who love reading. However it is a very depressing story and the ending definitely leaves one feeling unsatisfied. The story of a family over 3 generations told from each perspective jumps through time but eventually culminates in the present with all the stories coming together, this is done fluidly and never feels jarring. It's also a story of mental illness, homelessness and the links bwteen the two, and in this vein it's clearly well researched. Top marks for writing for sure, but a bit lower for plot. I always prefer stories with a more closed ending and found I was lacking some resolution for the characters. There was also points where characters developed during time jumps which I though could be more involved. I'll read more McCann in the future with great enthusiasm but I doubt I'll  re-read this book, despite how good it was.
