I picked this up because I had read her "Impossible Things" and liked it, also because I liked the brief on the back cover. I give this a two star rating rather than a one because the subject matter is interesting. The chapters go on and on longer than they need to and the book sometimes seems like a first draft rather than a final copy because there are many things that haven't been taken out. I sped through the last 80 pages not because I was gripped by the book, but rather, after reading the first 700 pages, I had invested too much and just wanted to be through with it.
