Yoto Carnegie Medal Shortlist * New York Public Library Best Book of the Year * Kirkus Best Book of the Year * School Library Journal Best Book of the Year * My sister tells me the rules of the game are simple. Avoid the monsters. Don't get caught. And keep moving. If the monsters catch you, you're out. A young boy and his older sister have left home to play a game. To win, they must travel across endless lands together and make it to the finish line. Each child imagines what might be waiting for them across the border: A spotted dog? Ice cream! Or maybe a new school. But the journey is difficult, and the monsters are realer than they imagined. And when it no longer feels like a game, the two children must still find a way to forge ahead. ★ "The story is ultimately hopeful, gently providing probing insight into the lives of the youngest migrants." --Kirkus Reviews (starred review) ★ "Beautiful, timely, and poignant. Recommended for all collections." --School Library Journal Online (starred review) ★ "Powerful. It's a realistic but hopeful look at two children's emigration."-- Publishers Weekly (starred review)
