peopleâs houses in the middle of the night and did things like change the furniture and shrink all their clothes and dye their pets green, so when the people woke up they believed they were in some bizarro world. More than one contestant had gone totally insane. Those who didnât go insane won a vacation or a new toaster.
Celia was not interested in a vacation or a new toaster. Oliver was looking around for hidden cameras.
âWho are you?â asked Oliver
âHow did you know weâd be here?â asked Celia.
âYour friend told us.â The boy shrugged.
âOur friend?â Celia cocked her head to the side like a confused puppy.
She and Oliver didnât have a lot of friends in the sixth grade. Their father had pulled them out of school to go on adventures for most of the school year, and when they were in school, most of the kids only talked to them because they knew Corey Brandt. Celia didnât expect any of the squeaky girls who had Coreyâs face on their notebooks to know any Dinka warriors, and Oliver was pretty sure that none of the boys in his class had ever been to the Bahr al-Ghazal region of southern Sudan. Most of them werenât even allowed to ride the subway alone.
âCelia!â A girl dressed in a flowing white tunic with a colorful cloth bag over her shoulder climbed up on the other side of the roof.
Celia broke into a smile when she saw the girl. She wasnât a Dinka warrior and she wasnât from Oliver and Celiaâs school either.
âQui!â Celia smiled at her old friend from the Amazon, whose whole name was Quinuama, but she let people call her Qui to make it easier for them. She was thoughtful that way, even though she quite liked her full name. Qui had helped Oliver and Celia find the lost city of El Dorado in the Amazon and she was their first real friend in the world. Celia had no idea how Qui had gotten all the way to North Africa, or why.
Celia ran across the roof and gave her a hug. Friends, we should note, never start by asking why.
Oliver interrupted the hug. âWhat are you doing here? How do you know these warriors?â
âWe met on the Internet,â Qui answered him with a shrug.
âThe Internet?â Oliver and Celia asked.
âWe use it all the time,â said Qui. âWe indigenous peoples have to stick together.â
âIndigenous?â Oliver looked at his sister.
âYou know that one,â she said.
âLike native?â said Oliver. Celia nodded.
âMy people are facing many of the problems the Dinka and other tribes are facing,â said Qui. âFrom pollution and the destruction of our cultures to getting into a good college when youâve lived your whole life in the jungle.â
âOr in the desert,â said the Dinka boy.
âRight,â said Qui. âItâs hard being an indigenous kid these days. So we have Internet forums and stuff. Thatâs where I met these guys.â She pointed to the Dinka warriors.
âAnd where I learned about your prophecy,â the boy said.
âThe greatest explorers shall be the least. The old ways shall come to nothing, while new visions reveal everything. All that is known will be unknown and what was lost will be found.â
âThat prophecy is, like, mega.â Corey Brandt whistled.
âWe know.â Celia groaned.
âI canât believe you read our prophecy on the Internet,â said Oliver. âIsnât that, like, a violation of privacy?â
Qui shrugged.
âDo we really still have to do this whole prophecy thing?â said Celia. âIt seems kind of worn out.â
âHoney.â Her mother held her shoulders. âYou have to fulfill a prophecy before it can be over.â
âThat is so totally unfair,â said Celia.
âYou say that a lot,â said her father.
âWell.â Celia shrugged. âEverybody needs a catchphrase.â
Suddenly,
