The Battle of the Labyrinth (Percy Jackson and the Olympians, #4)

by Rick Riordan

“One game of rock, paper, scissors,” I blurted out. “If I win, you come with us. If I lose, we’ll leave you in jail.” Annabeth looked at me like I was crazy. Briares’s face morphed to doubtful. “I always win rock, paper, scissors.” “Then let’s do it!” I pounded my fist in my palm three times. Briares did the same with all one hundred hands, which sounded like an army marching three steps forward. He came up with a whole avalanche of rocks, a classroom set of scissors, and enough paper to make a fleet of airplanes. “I told you,” he said sadly. “I always—” His face morphed to confusion. “What is that you made?” “A gun,” I told him, showing him my finger gun. It was a trick Paul Blofis had pulled on me, but I wasn’t going to tell him that. “A gun beats anything.”
