About the Author
Strays and wanderers are often sent by the gods.
UNTIL SHE MET THE EXPLODING STATUE, Annabeth thought
she was prepared for anything.
She’d paced the deck of their flying warship, the
Argo II, checking and double-checking the ballistae to
make sure they were locked down. She confirmed that
the white “We come in peace” flag was flying from the
mast. She reviewed the plan with the rest of the crew—
and the backup plan, and the backup plan for the

She’d asked Leo to send one of his special inventions

camp. Hopefully the message had gotten through. Leo
had wanted to paint a giant message on the bottom of
the hull—WASSUP? with a smiley face—but Annabeth
vetoed the idea. She wasn’t sure the Romans had a
sense of humor.
Too late to turn back now.
The clouds broke around their hull, revealing the
gold-and-green carpet of the Oakland Hills below
them. Annabeth gripped one of the bronze shields that
lined the starboard rail.
Her three crewmates took their places.
On the stern quarterdeck, Leo rushed...
