I need help!!

So...

At Christmas time, my family asked me to write a book. They already thought of the name, but nothing else. So I need some help. Desperately.

So the name they thought of is the Cookie Conspiracy. Yeah, it was Christmas time and we were eating a lot of cookies. :)

But I have no ideas for it as of yet. All I have in mind so far is that it's going to be a mystery. But other than that... Well...

If you have any ideas leave them in the comments section. And if this is ever good enough to publish and I choose one of your ideas, I'll thank you in the thanks section of the book. :) That's if it ever publishes. I might self-publish if I think it's good enough. So let those ideas come!!

Thanks so much!! Brookie
