** spoiler alert ** 
 I just loved "The Bookseller"! Read it in a day and just couldn't stop, I HAD to know what is real and what is not. And even though I do understand some of the critics I've read about it in this site (the "married life" seemed a little too perfect even though all the problemas that came along with it), I do think that it's all for a reason. 
 For me, the thing I thought about the most is how some of the things in the "married life" are not really "her" - for example, the clothes she wears are nothing like the clothes she (supposedly) actually likes and wears in her single/"real" life. But I just think it's because when her parents died (the thing that caused her need to escape to another world) she didn't want to just fix that - in her single life, not only she didn't have her mentally ill son but she didn't lose all the things that made her and individual and not just a mom/wife - the bookshop, the best friend, her style, her likes, her "me time"... I think that she lost all that in the married life when she started blaming herself for the illness of her son. She was never really at peace.
