“Look, Dad,” says Mika from the back. “Look at the faces!”
Scott adjusts the rear-view mirror. The last he checked, Mika was slumped in a chaos of Lego, two minifigures squabbling inches from his face. Now the boy is fully upright, forehead pressed to the window.
“What do you mean? What faces?”
“In the trees,” says the boy. “Bubbly heads poking out of the bark. Look, Dad, can you see?”

“They’re probably galls,” says Scott. “Some trees grow them in response to bacteria, insects, that sort of thing. It’s a kind of symbiosis: the trees grow galls to protect themselves, but the galls also protect the wasps, or the greenfly or whatever, by drawing them in, growing around them.”
