Review of 'Book-in-a-book/Pooh Goes Visiting (Book in a Book)' on 'Goodreads'
4 stars
Nice geeky story, Harry Potter meets a time machine kind of thing. Being a large book it allows it to expand the world and develop the characters nicely.
I'm already feeling like I'm missing some friends now that I've finished the book. :)
