Beta readers needed

I've been working on an urban fantasy story for our post-NaNoWriMo group.  I'm looking for constructive criticism.  "This stinks" is not constructive criticism, it's just rude.  "This stinks because of X, Y, and Z" is better, but still rude.  "I didn't get A, B, and C because of E and F, but I liked G" would be good.  I'm giving it a PG-13 rating for some of the imagery.

The story is set in a world where the magical community were outed on YouTube after being caught on a security camera.  The Twilight Queen, ruler of the Fae, did a TV interview to confirm that magic is real and fairies, trolls, and dwarves exist.  Both worlds are still adjusting to each other.  My story is about a man who tries to find a scientific basis for magic.  The word count is 4300 (or 11 printed pages) and it's called The Science Of Magic.

I'm not posting it here, but if you would like to read it and will give me some feedback on it, leave a comment and I'll send you a PDF copy.

Update 23rd March:

Thank you for volunteering!  I have enough readers for now.  Better get started on the next story...
