So, I must be writing from the hole in the ground because I never heard of THE GUERNSEY LITERARY AND POTATO PEEL PIE SOCIETY. However, the book that failed me was THE BRIDGES OF MADISON COUNTY.
It all depends on the story, if the story has hooked me than I probably won't even notice the errors, but if I am struggling with the story I will notice every little typo.
I don't care who you are - we will always have some typos in a manuscript - but if we can get them into the story...
