Hi GoGriddlers
It's one puzzle comprised of 100 parts - ID numbers 63482 to 63581.
When all 100 parts have been completed 19 letters are hidden within the completed 10x10 picture.
Some are obvious but some are difficult to see.
Unscramble the 19 letter anagram to discover 'What Book Is She Reading?'
The completed picture is also a clue to the answer.
If you're having difficulty unscrambling the anagram there are posts in the forum offering hints

Hope this helps.
