Thanks Rad_n_kes,

I found a book review for the book:

Looks interesting. I hope more people come out and talk about the inside story of how the palace functioned. This is still one of the biggest secrets of Nepali history. Now that we no longer have the monarchy, I hope many more people who had worked within the palace in their lifetimes will come out and tell their stories before they die about how the palace really functioned.
