I'd been reading this book off and on for about six months, having gone through a few periods of being too distracted to read, before I decided it was time to hunker down and finish it.
It's a bit tough in the beginning since the best character tragically exits the scene in the first section, and there is a bit of a grieving period. It takes a while to see what the other characters have to offer — through their raw, often ugly emotions — and then by the time you get behind them, there are layers of betrayals to contend with at the end.
There is so much in here, I'm sure I will read this again eventually. I think it's more of a summer book than a winter book — though it may just be the descriptions of Greenwich Village that make me think of summer.
