Harry's Pets by
Shadows In The Sun.
Summary: What if Harry was into "evil" pets?
Rec: Okay, first things first. Huge warning that this is, in some ways, truly awful. The author needs to be severely flogged with wet noodles until they cry for mercy or get a competent beta who knows what spell check and a dictionary are, etc., etc., so on and so forth. Yes, I cringe or shudder or roll my eyes into a headache each time I see stuff like "flue" and "fallow", but.... (I'm actually having a hard time keeping Nimby away from the keyboard with this one.)
On the bright side, I'm having a wonderful time reading it! I'm giggling like mad, I am. Think... the Addams family, but not.
