With a dragon here, and a dragon there, here a dragon, there a dragon...
To quote Snape, "It has merit."
Snicker. Sorry, I just had to use that line. It's just so perfectly Snape.
Okay, now for the story.
OMG! You got in not only Harry as animagus, but you gave him TWO dragon forms! Then you gave us a phoenix almost barbequed (snicker) and even more dragons. All in the beautiful time element of Edwardian England (or so it felt). Loved the centaur hansom driver, the way you snuck in the canon characters.
I am in absolute awe of anyone who can create non-canon Magic (far beyond my ability), not to mention the spells, the plants, the way this Magic is used... Kudos to you for that alone!
Then there are Draco and Narcissa, who are slightly the same as canon, yet also different. Really liked them by the end of the story.
LOVED Prospero. Until you uncovered him to be Harry, I was wondering if you might lend him to me for stud purposes. Mei-Ping is getting nesting feelings and I was hoping (sniff...guess not) to offer you the choice of litter. Now I know that Severus would not be very obliging. ;-)
Great story. Definitely at the head of the dragon point race.
