I woke up at some unknown hour of the day to thunder, the kind that vibrates through your very bones and leaves your hearing ringing.
Even though I'd been the only one asleep, I wasn't the only one that jumped up with a yell.
"Holy shit," hissed someone who'd come to loiter around the great hall, because what else do you do holed up in a hill?
Only Poseidon looked somewhat in control, eyes big as always, but mouth closed tight. His dry scales scratched against my skin as I sat up to look about blearily, heart pounding.
