I've created this forum with the purpose of providing some light relief.
This is where we can air our annoyance at the errors that find their way into books. Some of them are straightforward printing errors, some grammatical. Worse, however, are errors in plot, characterisation, and general background knowledge.
The solution is, of course, to e-mail the publisher with the ISBN, asking for the error to be corrected in a future reprint. But you know they'll not bother. So let's tell the world about these errors! Create a new message per book title, please.
