“Argh!“ Thalia pushed me, and a shock went through my body that blew me backward ten feet into the water. Some of the campers gasped. A couple of the Hunters stifled laughs.
"Sorry!” Thalia said, turning pale. “I didn’t mean to—”
Anger roared in my ears. A wave erupted from the creek, blasting into Thalia’s face and dousing her from head to toe.
I stood up. “Yeah,” I growled. “I didn’t mean to, either.”
Thalia was breathing heavily.
“Enough!” Chiron ordered.
But Thalia held out her spear. “You want some, Seaweed Brain?”
Somehow, it was okay when Annabeth called me that — at least, I’d gotten used to it — but hearing it from Thalia was not cool.
“Bring it on, Pinecone Face!”
