The Son of Neptune is the second volume in the Heroes of Olympus series, In the novel, someone transports Percy from his home Camp Half-Blood in New York to Camp Jupiter in Southern California. He ends up there with no memory except one name, Annabeth.
On his way to Camp Jupiter, he is chased by the gorgons and observes something extremely odd. He observed that when he killed them they would just reform and come back and attack him which was not possible.
He embarks on a quest to make sure monsters stay dead when they are killed with his new friends, Frank and Hazel. He goes to the north meeting foes and friends. He completes his quest and arrives at Camp Jupiter just in time to aid them at their time of greatest need, during a battle for survival. He regains his memory and meets his own friends from his original camp to lead an even larger quest to save the gods.
I highly recommend this book because it leads to an even bigger finale and the book along with many others in the series Also, this is a novel that really makes you want to keep reading until the book is over. I read this novel in a very short time because i was really hooked into the story.
