Summer book

I'm generally a huge fan of the New York Review of Books Classics line, but I have failed to grok Tove Jansson's the Summer Book. Consisting of a series of vignettes, it tells the story of a young girl and her aged grandmother on a island in Finland. The praise for the book is effusive, see for example this blog post, but I am just not seeing it. Of late I have been a bit agitated so I haven't been able to sink into prose and I suspect that this book requires lots of quiet and lying somewhere like a hammock. I actually bought this copy so maybe I will go back to it later.
