Where's the book?
You have to look...
Don't be a sook,
Find the book!
The book "I ❤ Geocaching" has gone missing
The Dewey system is used by librarians to catalogue books in the library. You need to find the book and put it in the correct Dewey location. When you are correct you will learn the location of the cache.
To find the cache complete the Wherigo cartridge found here (username and password is the same as you use on www.geocaching.com).
