They got out of the Camp van at the sea-port (Percy doesn't fly unless it's on a Pegasus... Zeus might zap him down......) and Percy immediately felt better. Yes, it would have been quicker to get to England by plane, but...
"Well, which ferry is it? Or are we going by the under-water-breathing, somehow-keeping-clothes-dry Percy Express?" Asked Grover, jokingly.
"We are getting on a ship, G-Man... but... which one, Annabeth?" Laughed Percy- both answering Grover's question, and asking Annabeth a question. He laughed sheepishly as Annabeth drew her knife, looking directly at Percy, deep in thought.
"Woah! No need for violence!" Squeaked Grover.
"Don't be such a wuss!" Commanded Annabeth, grinning sadistically," I'm just thinking!"
"Oh, okay. Which one then?" Persisted Percy.
"4th one down from here... the one that says... I think Eglndan...?" Answered Annabeth.
"It says England, Annabeth." Grinned Grover. (All Demi-gods are dyslexic and ADHD, since their brains are hard-wired for Ancient Greek, and they're impulsive, and can't be still. Natural battle reflexes, they are- and will keep them alive in a fight)

They were just settling down in the canteen:Percy with a beef-burger and fries, Annabeth with a salad and taco and Grover with enchiladas and tin cans- when over the loudspeaker came;
"Could Percy Jackson, Annabeth Chase and Grover Underwood please report to the Captain's Cabin, immediately!"
Annabeth gave the two boys a glance, which said;this can't be good...

They arrived and held their breath as Percy knocked.
"Enter!" Called a gruff voice, which made it clear that it was an order, and not an invite.
