3 friends: Kelly, Hannah and Darbie have been chosen to be the protectors of the cookbook again. They're very happy and pleased about it. But then, the cookbook goes missing! They look for it everywhere, but it's nowhere to be seen! How awful! Has the cookbook left them? Was it a joke or something? Or- is it stolen?! Will the 3 friends be able to answer these questions, and find the cookbook? It's a real mystery...
