In this third installment of the Percy Jackson & The Olympians series, the plot thickens. New demigods are introduced, and some of them leave; the war against Olympus gains momentum, and our heroes must cross the continent once again.
Also, part of Hercules' mythology and some key elements of the Titan war take center stage, as our heroes meet and need to work with Artemis and her Hunters. Oh, and did I mention we finally get to meet Artemis and Apollo?
As always, a fun read full of action, adventure and almost deadly hijinks.
