Life In 19x19

I was checking A. Dinerchtein, since he's been posting some analysis of late and it had been quite a while (as in... 5-6 years?) since I last checked what he was doing. And I found there had been a PDF on hi site (I apparently can no longer access it) of a book titled '9 Graceful Solutions', by Grishin, Donskov and Emelyanov. The book seems available on Amazon, these days.

Has anyone checked it? The search function doesn't return me any mention, here.

Thanks. Take care
