Inaccuracies in books

I have just finished "The May Bride" by Suzannah Dunn which is the story of Jane Seymour, but Dunn has written an historical novel and given the characters modern day speech, so characters comment on a pregnant woman's "bump", or say things like "he's a decent bloke", and "Time to grow up, sunshine!" Aaaaarrrgh. It drove me mad and I had to force myself to finish the book but I won't be reading any more of hers.

It seems I am to have no respite because I have just started "The Heart's Invisible Furies" which has annoying errors as Farmor15 mentions above.

The new Mary Queen of Scots film having the tow queens meet and giving Mary a Scottish accent when she grew up in France .I know its not a documentary but there are those who will believe every word...like they did about Wallace ...when wee Mel Gibson played the man who was a tall person.
The other film that really annoyed me was My Sisters Keeper where they changed the ending and spoiled the story .Why do they do this?

I loved The long white cloud series I don’t think I m observant enough to notice things like that I just get lost in the story probably says more about me than the author I do think I d notice about decimal money though

Yes and spelling errors or the use of incorrect words. Spoils my enjoyment of the book.

I find it extremely annoying too!
Some of the obvious mistakes you have pointed out are ludicrous - don't these authors do any research at all?

I started reading a book called In the Land of the Long White Cloud set in the early days of New Zealand. It has some modern-day American expressions in conversations in the book which just spoil it for me.

I've abandoned it in favour of a terrific book written by one of our very own Gransnetters!
