Cashore is one of those writers whose books I find I like less and less the older I get. Which is a bit rare for me; usually when I fall in love with a book and its characters it's forever. But Cashore's books seem to be an exception. 
 Its not that there is anything inherently wrong with the plot, characteriaztion or creativity in Fire; in fact I feel it only fair to mention that these things were the very reason I enjoyed it so much in my late teens when I first read it. The problem is that I don't think Cashore is able to separate her super feminist voice and ideals from her characters and prose even when it would benefit the story. 
 I've begun to notice a trend where her characters HAVE to be modern in thinking, despite the lack of modern setting, to the point where she will literally shoehorn it in. Fire herself isn't the borderline husband and children hating person Katsa from Graceling was, in fact, she WANTS kids and can't have them for plot reasons, but she still talks a bit like Katsa would when the plot should call for it. 
 After a while I find myself annoyed with the constant "free love" and "I am not a monster hear me roar" mentality the book is over peppered with. The more I reread it as an adult, the less relatable I find it, and the more I realize how much annoying protagonist (and author) centered mortality is shoveled into this. 
 That said the writing itself from a technical standpoint is quite good and has held up well, I do like some of the characterization (its better than Graceling was), and the concept of brightly colored monsters is kind of neat though not as mind bogglingly cool as "graces".
