Thank you for writing for me!
First of all: You are under no obligation to include every character I requested in whichever fandom you choose! I was informed of that rule after the second time I'd put my request through, so I just figured I'd say it here, instead.
I'd love some good slash or gen fic in any of the three fandoms I requested (make that slash, gen, or het in the Eight Cousins fandom). Here are a few more details to get you started.
Eight Cousins Mac is hands-down, absolutely my favorite character in the series, so if you can include him in a major role and/or write from his POV, I'd love that. All of the characters I requested are inherently flawed in their own ways, no matter how they may struggle, so feel free to include plenty of moral wibbling/skewed thinking/poor decisions/regrets. But they're all good people at heart, too--yes, even Charlie. An explicit rating would be fabulous in this fandom.
History Boys In this fandom, it's all about Irwin for me--there's just so much going on with him, so much that is repressed and never quite acknowledged out loud. I'm intrigued with Dakin and Posner as well, if you can make them well-rounded. Any rating is great, from the most g-rated of genfic to the most explicit slash.
Wonder Boys Exactly what I wrote in my request is exactly what I'd like to see here! Awkwardness is gold.
Here is a little more information about my fic preferences, and though it's HP-centric, as that is my main fandom, it might give you a few more ideas.
