Percy approved whole heartedly of Dawn's plan. She wondered if that was a good thing or a bad thing. Percy was a troublemaker-you could tell by his bad-boy smile. She didn't want to get kicked out of camp but she had to find Leo. At least he had agreed to help her out.
'Dawn! You're not paying attention, are you?'
Annabeth's voice rang in her ears and she started and sat up. 'What?'
Her friend sighed. 'What did I just say?'
'Oh-um...' Dawn tried to remember. 'Wasn't it something about Hydras?'
Annabeth rolled her eyes. 'That was five minutes ago.'
'Sorry.'
Annabeth looked at her, scrutinizing her as if she were an interesting specimen. Dawn coughed.
'Something's bothering you, isn't it?' The daughter of Athena finally asked.
She fixed her gaze on the creek, whose banks they were sitting on as she had her first Greek Mythology lesson.
'We-ell..yeah,' she said.
'What is it?'
Dawn couldn't tell her the truth-or at least not all of it.
'I was thinking about the prophecy,' she answered carefully. 'The words "the fifth since the curse" and "the one who conceals". What do they mean?'
Annabeth frowned, considering. Dawn was glad she had got her away from the topic of Greek mythology.
'I didn't think much about them, actually,' she admitted, giving her a look of grudging admiration. 'Might be a daughter of Athena. Anyway, I'm not sure about the fifth since the curse. But Greek for the one who conceals is kalypto. Must be...Calypso.'
Was she imagining it or did Annabeth have a decidedly sour look on her face at Calypso's name?
'Who's Calypso?'
Then, of course, the entire story of the Giant War had to be told. Dawn was amazed at what Leo had done. Her respect of him increased immediately.
'...and that must mean he went back to Ogygia, got her and is coming to Camp Half-Blood. But Festus can fly really fast. Leo would've arrived weeks ago unless something had stopped him.'
'A prison guarded by a fearsome foe...' Dawn's eyes widened. She looked at Annabeth for confirmation.
'I guess Leo's in there, then,' her friend didn't sound very cheerful. 'But there are a whole bunch of enemies this could mean.'
She suddenly felt queasy. Riding off on Carrie to rescue Leo(and possibly Calypso)was one thing. A 'fearsome foe' was another. Dawn was tempted to forget about it, sit back and wait for 'sunlight's daughter' to do the dirty work. Then she looked at Annabeth and thought about all she had done. Her friend had trudged through Tartarus....and she wasn't up for one quest?
'One quest that could get you killed,' the logical part of her brain reminded her.
'Shut up,' the illogical part told the logical part. 'I'm going to do this.'
'The curse is probably the Hephaestus cabin's curse!' Annabeth suddenly said. 'And the prophecy must mean the fifth new Hephaestus kid since the start of the curse. I'm going to ask Nyssa if Leo was the fifth new kid. She's head counselor now Leo isn't here.'
She jumped to her feet and headed off. Dawn grinned, watching her go. Annabeth had forgotten all about the lesson-which she suspected was a rare miracle. She had a half hour left.
And she knew exactly how she was going to spend it.

Percy looked alarmed when she told him what she and Annabeth had discovered about where Leo could be.
'Must have strong enchantments,' he said. 'We've tried to IM him a bunch of times and it's never worked.'
'But do you know where this prison could be?' Dawn asked. 'I mean-you've been through hell, literally. You've fought so many monsters there are probably only a handful you don't know personally. So, think about it. How many 'prisons' like that have you encountered?'
Percy considered.
'Well...the year before last, we were in the Labyrinth and-'he turned pale. 'Oh, this is not good. This is really not good.'
Dawn felt nervous. If whatever Percy was thinking was scaring even him, she didn't want to know what it was.
'What?' She asked anyway.
'Kampe,' he said simply.
'Kampe....Grover told me about her but he said you killed her! How can she be back so fast?'
'I don't know!' Percy smacked the edge of the canoe they were sitting in. 'I was hoping for at least a few centuries so I wouldn't be around to fight her again! But nooooo....she has to come back in two years' time!'
Dawn couldn't suppress a smile. Percy sounded like a little kid when he whined like that. Then she thought of Kampe and her smile faded.
'If she's back, why would she return to the prison in the Labyrinth?' She asked. 'She chained enemies of Kronos before, people like that Hundred-Handed One. What was his name-Brambles?'
'Briares,' Percy told her, too upset even to crack a smile.
'Yeah, him. Well, he's busy working in the Cyclopes' forge, right? And Kronos isn't around either, to have Kampe work for him. So why would she be guarding a prison now?'
'Dude, being smart is Annabeth's job!' Percy exclaimed. 'How am I supposed to-um, form a hypo-thingy or whatever it is you want me to do?'
'I think you mean hypothesis,' Dawn said, feeling suddenly tired.'Let's just get back to shore.'

As Dawn sat down at the Hermes table for lunch, she noticed how everyone was talking excitedly about something. They seemed to be pointing toward the Poseidon table. She glanced over, wondering what Percy had done, when she saw a huge guy with scruffy brown hair sitting next to him. He seemed to be eating a jar of peanut butter and talking to Percy at the same time.
Then he turned around and she gasped. He had one eye. One. Freaking. Eye.
'Oh my gods!' She squeaked.
Connor looked at her.
'Oh yeah, forgot to tell you, that's Tyson,' he said, waving his fork nonchalantly in the air and nearly taking out Travis's eye. 'Cyclops. Percy's half-brother. Works in the forges in Poseidon's palace underwater. Comes to visit sometimes.'
It took Dawn a minute to get used to the sight. Then she remembered what Grover had told her. She took a shaky breath and nodded as calmly as she could.
She got up to scrape some of her food into the brazier and mutter a quick prayer to her godly father, whoever he was, and then made her way to the Poseidon table. She kept an eye on the table where Chiron, Mr D. and some members of the Council of Cloven Elders (including Grover) sat but it didn't matter. They had finished eating and were playing pinochle, which was apparently so absorbing that even Chiron forgot to keep an eye on the demigods.
'Hey,' Percy said casually as if he wasn't sitting next to a Cyclops and-she had just noticed her-a skinny bird with a woman's head and red feathers?
'Hey,' she replied, slipping onto the bench opposite him. She looked at Tyson. 'Hello.'
From close quarters, he lost most of the ferocity he seemed (A/N:Notice I said 'seemed', okay?) to give off from a distance and gained an adorable-oversized-toddler sort of look. His huge eye was so meltingly brown she wondered if Percy ever won an argument with him. He gave her a tentative smile.
On his shoulder perched the bird-woman-harpies, weren't they called?
Then she remembered what Annabeth had told her about the Giant War. She had just mentioned Ella as being a harpy, with Tyson and, of course, having memorized the -Sibling books? No, it was something else. Sibylline, possibly.
'Hello, Ella,' she said to the harpy.
'Hello,' Ella said to herself. 'UK magazine, started 1988...' She trailed off.
'Ella?' Tyson asked nervously.
The harpy looked up, saw Tyson looking at her and blushed.
'Ella likes books,' she announced, fidgeting a bit. 'Tyson likes peanut butter. Ella likes peanut butter too.'
Tyson immediately gave her his jar.
Dawn looked at Percy. She must have looked as confused as she felt because Percy answered before she could ask.
'We found Ella on the roof of a library. She'd memorized every book there. You can hardly say anything without having her quote a paragraph from a book. She's strange but she's really smart,' Percy added defensively.
Dawn smiled.
'Seems like it. Memorized every book there, huh? Wow.'
He looked relieved. She nodded at Tyson and Ella, who were sharing the jar now.
'What about them?'
'They've been dating for some time now,' Percy explained. 'Ella's even been enchanted by some Hecate kids so she can go to the underwater forges with Tyson when his visit is over, for some time.'
'A harpy underwater?' Dawn raised her eyebrows. 'That's not normal, is it?'
'Well..' Percy considered. 'I guess not. But Tyson and Ella aren't exactly normal, either. We're all a big, happy, really weird family here.'
Dawn couldn't help grinning at that. 'And am I an official member yet?'
Percy handed her half a sandwich. 'Of course you are. Welcome.'
She bit into the sandwich, looking at Tyson and Ella. 'Congratulations. I'm happy for you two.'
They smiled shyly at her.
'Ella likes Percy's friend,' the harpy put in.
'I like you too,' she answered agreeably. Percy laughed, Annabeth flashed an affectionate smile at them both from across the room, and Dawn felt full and warm and happy, with real friends at last.
