This is personally upsetting to me.
An author should have no reason to tell someone that they're illegally reading their books. There shouldn't be readers complaining that books cost too much, or that it takes too long to illegally download it. There's no reason for that. Book lovers should just love books - without illegal downloading having to be involved.
Piracy is an issue that many authors are dealing with every day. And now, lets say that you're a pirater. (pirater? pirateer? piracist?) I don't know what your reasons are. I'm not going to assume that you know what you're doing is wrong, because we all make mistakes, and obviously it doesn't make you a bad person. For all I know, you use it like a personal library - read, delete, buy it if you liked it. I don't know. I can't hold it against you. Hopefully you realize the error of your ways soon, though.
But seriously, stop this piracy - support the authors. You love their work, why not let them know by actually buying their books? Helping them pay their bills? In the words of Paula Stokes,
If 10,000 kids pirate your book, no one gets paid and maybe no one knows your book was popular. If 10,000 kids check your book out of the library, librarians notice and they order more copies, or they order your next book, or they read and nominate your book for awards, or they invite you to come speak, or they tell other librarians about your book, or they recommend your book to teens, who then maybe buy your next book or recommend it to more teens. Librarians can be incredibly powerful allies for authors, if you let them.
So, what if you illegally downloaded their book? And you really loved it. You're dying for the sequel to come out, so you can pirate it as well. But...the series gets discontinued. You never find out what happened, because the first book didn't sell enough copies. You contributed to that, however indirectly. You hurt the author. You hurt the series. And you'll never know what happens.
Think about that next time you try to get a "freebie". Remember, pirates had bad hygiene - and few friends.
Edit: I would like to state the fact that my opinion on this has changed since I've become a blogger. Before then, I really didn't think it mattered. By becoming a blogger, it's made me realize the effect that simple things like this have on people. Just thought about this, after I posted the post.
