Just a clarification, I am not concerned so much with the odd typo like the quote marks; this was actual copy-editing errors in the content of the book, like Jimmy becoming Jimmie in a few places.
I emailed the author and got a very polite reply which basically said that he thanks me for writing, it is a pet peeve of his too, and the background is that editing is hard work and most e-publishers simply can't afford to hire proper people to do it. He encouraged me to keep reading because the world needs more readers
He seems like a nice guy, but I do not completely accept his explanation. If his 'publishing company' won't pay for an editor, than he needs to do what the more serious authors in the fanfiction community have been doing for years and get himself a beta reader. Perhaps he has a fan who would be willing to do a quick pass-through for him in exchange for a free copy of the book. Or perhaps, instead of writing more than 60 ebooks, he should focus on writing fewer and of higher quality. Or perhaps the ebook should be priced at a lower price point (if you are not a Fictionwise club member, it's about mass market paperback price) to reflect that we are not getting a commercial-quality product.
