New Post: Where can I find the sample data of the book《Analyzing Social Media Networks with NodeXL》?

I'm learning the book-Analyzing Social Media Networks with NodeXL: Insights from a Connected World. There are some sample data in the book, such as"SeriousEats_Example.xlsx" and "Les_
Miserables_Example.xlsx"...But I don't know where to download them. Can someone tell me the urls for the data? Thank you.
