The Grimm Conclusion by Adam Gidwitz

Adam Gidwitz's site can be found at http://www.adamgidwitz.com/ , and I was lucky enough to find a book trailer for this one! 



Also, incase you haven't read the first two books, check out their trailers as well. The First book is a Tale Dark and Grimm (which follows Hansel and Gretel) and the second is In a Glass Grimmly (which follows Jack and Jill).

Until next time, my Grimm readers,
