I want to take your fiction and make it as good as I am capable of. I want to make it as good as you are capable of. I want your readers to get to the end of every chapter you write without getting annoyed that you misplaced a comma, that you threw them out of the narrative or that your characters make them want to bludgeon something to death.
I'm reasonably good, but I'm harsh. Let me say it one more time, I'm harsh. And for the kids in the cheap seats, I'm harsh. You're warned.
Other than that? Erm, I'm British, so if you're not and you're writing in a fandom that is, I can Brit-pick. Conversely, if you're not American and you're writing in an American fandom, I can't Yank-pic for you.
Pr0n is fine, and I can reality check that.
I have a smattering of French and a smattering of Latin, but other than that I can't help with languages.
Contact wise, message with details of your fic (approximate length, fandom, pairing, basic plot) and your email address and I'll get back to you. Pretty constantly contactable by email, so the beta will be done when it's done, but you can check on my progress and I can check in with you.
