Elsewhere, Perenelle has been taken to a more secure prison.
Since she's locked up, she'll have to rely on her senses to suss out where she is. She smells salt on the air and hears a ship's horn.
Goodness. She's at the Rock. By which we mean Perenelle is being imprisoned on Alcatraz, one of the most famous prisons ever, located on a tiny island in the San Francisco Bay. (Be sure to check out our section on "Setting" for more on San Francisco landmarks in the novel.)
At first, Perenelle is surprised that no magic warding spells have been painted on the walls to contain her, and for a moment she thinks she can just walk out.
Filling the corridor is a giant creature—a huge Sphinx with the wings of the eagle and the head of the gorgeous woman.
The Sphinx reminds Perenelle that sphinxes absorb auric energy. In other words, Perenelle has no magical powers around the creature.
Perenelle shivers as she realizes that no one has ever escaped the Rock alive.
