As for answer 2, I've shown what basic searches can come up with. "why im not a feminst" might give you what you're looking for.
Answer 2: So I did the Google search as you requested, and read about the book [1]. I hadn't heard of it but it looks interesting, thanks for recommending. From what I can tell, it's central claim is that feminism has an image problem due to it being co-opted by the US right-wing which she calls "choice feminism", and the remedy is a need to return to a leftist concept of what she calls "radical feminism". Is that what you're saying?

The search for me at least brings a number of articles which highlight common criticisms of the movement such as rampant sexism, advocacy for abolition of basic rights (free speech, right to fair trial etc), general hypocrisy and bad faith action (see the Cathy Newman vs Jordan Peterson interview for a great example of this)
Perhaps when you search with your normal Google account it's skewing to different results. This particular book and the articles discussing it are critiquing modern feminist movements as too conservative, from what you perhaps would call a "radical left" perspective. I find it interesting that this is the exact opposite of "the general criticism at the moment seems to centre on the radical lefts takeover"!
I personally feel my incognito Google search captures the current zeitgeist better than your search, that people are fed up with conservatives and want a "radical, fearless call for revolution" as Google's auto-summary of my search put it. That said, ultimately it's all "bubbles" all the way down, as there's no such thing as a so-called "algorithm" (ranking formula, etc) free from ideology, so ¯\_(ツ)_/¯
All the other summaries on Amazon are similar, i.e. the very top description (New Yorker): "The point of 'Why I Am Not a Feminist' isn’t really that Crispin is not a feminist; it’s that she has no interest in being a part of a club that has opened its doors and lost sight of its politics—a club that would, if she weren’t so busy disavowing it, invite Kellyanne Conway in"
Having never read the book or even heard of the author until you introduced it to me I don't care one way or the other, but it's clear from a reading of these descriptions that her book is a critique from the left.
