It is not surprising that my kids really enjoy the irreverent and ghastly retellings of fairy tales in Adam Gidwitz's Grimm series.
The three Ravens watch a young boy share his overnight campfire in a creepy wood with three dead men. And, of course, they engage in witty banter. (The Ravens converse, not the corpses- that would be implausible.)
I was busy just trying to draw Ravens, not Crows... or some other bird. I did not manage to make them look talkative...or witty.
