If you gave a mouse the equipment to speak, could he use it?

kw: book reviews, science fiction, fantasy, quests

Fourth World by Kate Thompson is billed as science fiction, but the element of fantasy is rather strong in her writing. This is the first novel in a trilogy called "Missing Link". Danny, a seemingly handicapped boy, helped by his stepbrother Christy and some decidedly odd companions travel from Ireland to Scotland across a near-future Britain in the grip of energy-crisis rationing (forget £2-per-liter petrol; there is nearly none to be had at any price), in search of Danny's mother. Two of the companions are a dog and starling that can speak.

More than half the novel is taken up with their journey. When they arrive, they find a lot more speaking animals, including a pink, hairless mouse that befriends Christy. Now, with the starling I already drew the line. The mouse is a step way to far. Unless we have greatly misunderstood how brains work, there simply isn't enough gray matter in the brain of any small creature to manage the thinking that underlies speech. Perhaps the mouse looks like "The Brain" in the cartoon...

A second scientific quibble I have is with the notion that the Missing Link between humans and apes is defined by exactly one gene, that supposedly endows humans with the power of self-reflective thought and speech. The current understanding in Anthropology circles is that there are at least twenty known links between humans and the proto-hominid that is ancestral to both humans and chimpanzees. The genetic difference between people and chimps is a bit over two percent, meaning major differences in about five hundred of the 22,000 or so "genes" that define each species. Even in 2000, when this book was released, we knew that it takes a few hundred genes at least to differentiate humans from apes.

Oh, well. Thompson is a skilled writer. With a bit of struggle, I could at least set aside disbelief and enjoy the yarn. The twist at the end, revealing why Danny can hold his breath so long, is satisfying. I guess I'll hunt up the other two novels.
