I am currently reading a book that came highly recommended. I have to say, I'm really enjoying it - except for one, teeny, tiny, niggling point... koala's aren't bears!
In the book the author makes a reference to "koala bears". She did that many pages ago but I can't let it go. So please excuse my little lecture.
Bears are mammals. They give birth to live young who have developed in-utero receiving nutrients via a placenta.
Koalas are marsupials. They give birth to live young who haven't received nutrients in-utero via a placenta. Instead the young are born much earlier than mammals (an earlier embryonic stage) and travel to a pouch where they attach themselves to a teat and remain there for weeks or months to complete their development.
Like I said, only a teeny point. But as an Australian reader it grated and pulled me from the story. Not helped by the fact I am also an environmental scientist, which is probably why I haven't been able to let it go.
I guess it just shows that readers will notice any error that slips through edits.
Has an incorrect fact in a book ever distracted you from the story?
