The book Hush Hush by Becca Fitzpatrick?

i was wondering if anyone had any ideas for a book project? It can be anything, like my friend read the book Hoot and its about owls laying eggs in the ground. So she took a shoe box and filled it with dirt and place little owls on it. So then my teacher as to find things in the dirt. Any ideas that i can do for Hush, Hush??
