Love the plot, the smex, Hermione and Ron (and Harry with his godchildren - sweeeet!), and the negotiations with the ICW and the demon. Heh - which one was actually tougher? LOL. It was a GREAT demon scene, though, and those are really hard to do!
Most of all, however, I loved the Cherish Severus Snape Time here, there and everywhere in this fic. Yayyy for sexy bottom!Snape and a grown-up, take-charge Harry! I am totally bookmarking this fic so I can read it again whenever I need great Snarry!
