She’s right. There might be a scorch mark running across it, but it feels like it’s just come out of a tumble dryer. For a moment I close my eyes and enjoy the incredible sensation of warm fluffy fur. Now I’m not cold I can start to be grateful to Win. “Nice magic, mate,” I say, clapping a hand on his shoulder.

“I know,” he says, nodding, “and now we’ve also got a useful hole in the raft.”

Luckily the hole doesn’t make the raft sink, but icy water does shoot through it every now and then.

It’s creepy being in the dark surrounded by water, but we decide not to use Mitch’s magic bottle of light. We’re not sure how long it will last and when we might need it. Instead we slip along in the pitch black and talk about how spectacularly badly our mission has gone.

“Crowky’s got the Box,” says Rose, not that I needed reminding.

“We’re being chased by an aggressive girl and her wolves,” I add.

“And we’re on a chunk of ice floating along a river in a mountain and we don’t know where we are!” Win adds gleefully. “What an adventure . . .”

At that moment our raft bangs into something, spins around, then bashes against something else, and we decide it’s time to use Mitch’s magic bottle.

Rose gives it a shake and the bright light appears. Now we can see that the underground river has gotten wider and sharp rocks are sticking out of the water. The river is flowing too fast for us to stop moving, so all we can do is shift our weight from side to side to try to avoid the rocks. This works for a while, but soon there are just too many rocks and we start banging against them.

We huddle together in the middle of the raft, water sloshing through the hole, hoping we don’t tip over. Then we spot a pink light glowing in the distance.

Rose puts the bottle away and the light becomes clearer. It might be tiny, but it’s a brilliant sight because it looks like, finally, we’re coming to the end of the tunnel. As we drift forward we start talking over each other as we wonder what we’re going to find on the other side of the mountain.

“There might be a town full of wizards!” says Win.

“Or lizards,” I suggest.

“Or fairies,” says Rose. “Remember my fairy game, Arthur? That’s got to be here somewhere.”

I definitely sent Rose’s fairies to the End after they appeared in Roar because they were really violent and scary. For a while Rose and I reminisce about the fairies, forgetting for a moment that Win is listening to us.

“I don’t get it,” he says, interrupting us. “Why would Rose’s fairy game turn up in Roar?”
