That's certainly a new approach. I liked it, and I even recognized where it takes place in the books. Oh and uh, you called the owl, he, once... just thought I would let you know.

Author's Response: Thank you :] It was probably just a typo. Whoops. >.>

Your owl seems very clever and is written well - it must be quite hard to write about an owl!
First off, some nit-picks.
The boys looked at each other with wicked grins said, “Looks like this one is eager for the job.”
This sentence is awkward, and confusing. Do you mean: The boys looked at each other with wicked grins and said, “Looks like this one is eager for the job.” or The boys who looked at each other with wicked grins said, “Looks like this one is eager for the job.” ? Either of them would work better than your original sentence.
Also, you seem to begin your paragraphs with a lot of 'The owl' and 'The boys'...it can get a little annoying, so I would suggest playing around with words.
As I have said before, your owl is amazing. She's clever and determined, and her acts almost seem human! (In a good way, of course)
I also like the settings you chose - Bagman and thw Twins are a very rare combination that is hardly ever explored by fanfic writers.
Kepp up the good work!
