I had a few expectations as to an ending, and was greatly satisfied to not see the ending as I had imagined. 
 I love happy endings. I really do. And I love them even more when they are preceded by so much heartache, misery, and sacrifice. Such a happy reversal was not forced in this novel. There was much time and effort devoted to it, with careful plotting and recognition of consequences. This, more than anything, was a much more satisfying than the official resolution of action. Hell, the main climax came two-thirds into the novel, and the resolution could have filled a more traditional-length novel. 
 I actually loved the departure, and despite the blatant wish-fulfillment kind of ending, I am happy. I am satisfied. Molly may not be a fully realized character the way I'd wish, but her evident regard of poor old Fitz is still heartening.
