Recess is wholly transformed when Omeed holds up an orange and asks one question: "What if this were the world?"

Ms. Lee's class had come perilously close to running out of games, but the hunt for the best world gains steam right away. The orange is tasty, but too small to share. A dodgeball world can be punted to outer space by a mean older kid. A maple tree isn't portable enough.

Imaginations have never been so alive. But still no perfect world turns up, and the kids' search is leaving a trail of litter and destruction behind them. Maybe there really is only one world that ticks all the boxes, only one world where everyone fits and can get what they need. . . and maybe it's time to treat it a little better.

With a cast of big personalities and a hearty helping of witty banter, If This Were the World reads like the very best recess, with a well-earned nod to our planet and the work of protecting it.
