I don't know anything about publishing a book but I presume books are proof read before being published. I read 2 or 3 fiction books a month. I have seen spelling and grammar mistakes a number of times and can't understand how nobody seems to have noticed before publishing. Sometimes a name can change! One book I read, Edward became Joe for a couple of sentences then returned to being Edward! One author seems to think affair has an e kn the end to make affaire, this is in at least 3 of her books!
Aibu?
