I thought this book would be more in depth, but knowing now that it is probably a middle grade level book, I'm deeming it a three star. I am hopefully soon going to read Cottingley Secret as I find it fascinating that two young girls have duped the world, with Sir Author Conan Doyle at the helm of those who were tricked. I wanted to get some background information before I read the book, and this was a very quick, basic read about the actual event. It's good, the pictures are interesting (to say the least, as they were the basis of the belief in fairies), but again, the writing is definitely middle grade or upper elementary, so don't read the book looking for extensive research.
And the book was so small it helped me with my Goodreads challenge, so there's that.
