I didn't find this prequel until I was already into Mila 2.0, and I found it fascinating, but I think it will be more interesting for readers once they already know something of the story--I'd start with the book excerpt rather than the prequel to get an idea if Mila 2.0 is for you. The prequel answered some questions for me, and interestingly enough raised others, but it's a little weak by itself and doesn't showcase all the strengths of book.
