Blood of the Earth

Percy Jackson was never supposed to be the responsible one.
He was supposed to be dead, or at least moderately maimed, after twelve years of wolf-goddess boot camp and a brief but enthusiastic career of making Olympus nervous. Instead, he became Imperator of Rome at sixteen, acquired a Bugatti he can't legally drive, and entered a relationship with a Praetor who absolutely terrifies him-in a fun way.
The job mostly involves killing monsters, ignoring the Senate, and wearing the same pair of gray pajama pants for three days straight.
Then the Greeks show up with their flying boat, their lightning bolts, and their complete inability to ask for directions. One banquet later, New Rome is on fire, someone has declared war, and Percy has decided-entirely uninvited-that he's joining their quest.
Now he's trapped on a ship with seven people who flinch when he moves too fast, heading toward Rome to fight giants, decode prophecies, and rescue a boy who is currently napping inside a very expensive jar. Percy has weapons for everyone, prophecies for the unlucky, and absolutely no intention of following anyone else's plan.
There will be steak. There will be poor decisions. There will be at least one divine being reduced to tears.
