I can here those woodland creature wheels a'spinning as you read this tweet.
Here's what you need to know:
1. When you have an offer from an agent, you SHOULD let other agents reading your work know about it. There are numerous posts on how to do that here on the blog.
2. If you're ever tempted to say you have an offer when you don't, DO NOT DO IT.
For starters, publishing is not like any other kind of business where this kind of chicanery might be seen as business as usual. It's the exact opposite.
And, unless you have an offer in hand, you won't know how to answer any questions about it, and that will give your little game away instantly.
And, most important from your point of view, it will not get us reading faster. It will get us passing faster. This is the time of year when if you want me to read something quickly, I have to say no.
Bottom line: There are very few things that will get you blacklisted by agents. Lying like this is one of them.
I know the readers of this blog would never do such a thing.
The purpose of this post is to tell you that we, on this side of the desk, can distinguish between the skulduggery of invented offers and the email you send when you have (a legit) offer.
Don't let this one writer's idiocy and the furor it created bother you. Just sit back and know that you're a whole lot smarter than s/he was.
