The lady in green armor stared at me coldly, then crossed her arms and said,

"Excuse me, my lord. I am needed in the battle."

 

She swam away.

 

I felt pretty awkward, but I guess I couldn't blame her. I'd never thought about

it much, but my dad had an immortal wife. All his romances with mortals,

including with my mom . . . well, Amphitrite probably didn't like that much.

 

Poseidon cleared his throat. "Yes, well . . . and this is my son Triton. Er, my

other son."

 

"Your son and heir," the green dude corrected. His double fish tails swished

back and forth. He smiled at me, but there was no friendliness in his eyes.

"Hello, Perseus Jackson. Come to help at last?"

 

He acted like I was late or lazy. If you can blush underwater, I probably did.

 

"Tell me what to do," I said.

 

Triton smiled like that was a cute suggestion — like I was a slightly amusing

dog that had barked for him or something. He turned to Poseidon. "I will see to

the front line, Father. Don't worry, / will not fail."
