I recently beta read a book for a friend, and now comes the difficult part - writing about his work. I left comments in the document as I went along, but I'd like to include in my e-mail a basic overview of what I found. But it's really, really hard to write. What should I mention first, what tone should I use? Plus, while I loved the book, I read it with the mind set of critiquing it so what's stuck in my head more has been what could be fixed than what went right. But I don't want to give this big list of what's wrong. I want to be balanced, and supportive.
So, what would you guys as authors like to see from your beta readers? Do you even want an e-mail, or maybe just the marked up copy? Do you want lots of details? (in a creative writing class I took, we had to list three faults and three good things and the later tended to be things like 'the imagery was great, especially this line: line) Or just an overview? Funny little comments? What would make you feel better about opening an e-mail you've noticed the last three times you logged onto hotmail and decided again opening?
