Of the last 10 books that I have read I have found typos in 9 (and it was really late when I read the other, so who knows what I might have missed). Now, I don't claim to be perfect, but your job is to edit. Please do so more thoroughly. If you are afraid you might have missed something, please send the book my way. I'll check it out for you before you send it to the general public with a glaring mistake that would disrupt the reading enjoyment for them.
