I must go hunt the creature of the Great Stirring by myself.
I am very sorry to have to say this, Zoe, but Lady Artemis has disappeared!
Percy, Thalia, Grover, and Annabeth had just saved Bianca and Nico Di Angelo from Dr. Thorn who was really working for Kronos. But while they were fighting, Lady Artemis shows up with her hunters to help them but Annabeth, who was on Dr.Thorn's back, falls over the cliff with Dr.Thorn.
Percy, Thalia and Grover return to Camp Half Blood with the Hunters when they find out that Artemis disappeared during her hunt. "Five shall go west to the goddess in chains, one shall be lost in the land without rain, The bane of Olympus shows the trail, Campers and Hunters combined prevail, The Titan's curse one must withstand, And one shall perish by a parent's hand" After hearing this prophecy, Zoe, Bianca, Thalia,and Grover set out on the quest to find Artemis.
