Others have summarised the plot well. Iโm in the Confused group. Too many subplots, too many characters, too long. Was it Ada from India who drowned? I forgot who was reappeared-at-the-end Leonard. And what was the role of Pale Joe? Iโm going to guess that Best Seller Kate received a big advance from publisher Atria, but had one too many extended deadlines. So she tried to knot up all the strands, but forgot where she put her knitting needles.
The writing is beautiful. The construction is not.
