Query: Funny and Tragic

I was hooked from the first line, and didn't stop until the last one. This unprecedented, no-holds-barred glimpse into the rarefied world of the uber wealthy made me actually glad that I am not "one of them". And knowing, despite claims to the contrary, that this story was based on real people and real events, made me feel sorry for the children of these narcissistic, hedonistic, soulless billionaires who think that money buys good parenting. My heart ached for Grayer; and I was actually a little emotional at the end. And it made me want to be a better mother.Well written, funny, and heart-breaking. Everything a good book should be.
