I just finished reading "A Tale Dark and Grimm" by Adam Gidwitz.
All I can say is WOW.
The entire book is written in third person, such as any age old fairy tale. It follows Hansel and Gretel through multiple fairy tales that intertwine and weave their coming of age stories together. Though merely children, Hansel and Gretel aren't given any mercy (which is yet another reason to live Grimm's fairy tales), and the entire novel is filled with incredible challenges that the reader can't help but wonder, "How in the world will they get out of this?"
Gidwitz also does a wonderful job of balancing dark with light with hilarious commentary throughout the entire novel.
Please Adam Gidwitz, write another one!
