The Amazing Bone
Bones are people-- er, pigs-- too.
This is a weird book. It's a world of anthropomorphic animals. The main character is a young pig lass who is on the way home from school. She hangs out in the forest and says, "I love everything!" And then a voice says, "So do I!" And she says, "Where are you?" because she can't see anyone. It turns out to be a talking bone. That can imitate any sound. And that's pretty much all it does. It's a magic, talking, intelligent bone. It doesn't even say what it's a bone of. She even asks it how it can make noises, and it says, "I don't know. I didn't make the world." So there's no explanation for it. The bone had originally belonged to a witch, but she dropped it and the bone wanted to be free of her so it didn't call out to her. And Pearl the pig befriends the bone, and it scares off some robbers who attack her. Then she and the bone are captured by a fox, who discovers that she has a talking bone and is just like, "Whatever," and is not afraid of it. Then she gets taken home by the fox and the bone realizes out of nowhere that it can cast magic spells, probably since it hung out with a witch for a long time, and then she escapes and takes it home and it becomes part of her family. The end.
So, yeah. Very deus ex machina ending there, coming out of nowhere. We have a bone and talking animals, and the bone is magic and can imitate sounds, and all of a sudden it can cast spells. But it doesn't know how it knows the spells, or what spells it knows. It apparently only casts them in times of great distress.
