This is an wasome book. It is for ages 7 and up if your a good reader. It is my favorite book of Heros of Olympos. It is about how Rena, Nico, and Coach Hedge are trying to ruturn a magical statue to Camp Half Blood in order to make peace with the Romans. But on the way they are noticing Nico is starting to fade and the Roman Octovon has filthy plans to destroy the camp. Will they return the statue in time to make peace? There is also other problems the Argo 2 ships crew is trying to stop Gea from waking. Will the Romans and Greeks make peace to fix the gods and stop Gea or will Gea win and destroy everything? My favorite part is when all of the gods like an army of gods rush in to stop the Giants and work with their kids! This is a great action packed, Greek Mythology and awsome book that I am sure you will love!

I loved this book so so so much. The main characters in this book are Percy, Jason, Annabeth, Reyna, Coach Hedge, Nico, Hazel, Piper, Leo, and Frank. These characters are all demigods, half God and half human. There are two kinds of demigods out of these characters -- Roman and Greek. They go to two different camps, Camp Jupiter and Camp Half Blood. They are going on two different quests out of two different groups. One of the groups is Reina, Coach Hedge, and Nico. The other group is everybody else. The first group is on a quest to deliver the Athena Pathenos to camp Half Blood to stop war between the Romans and the Greeks. The other quest is to stop Gaea from awakening. Gaea is an evil goddess, the Earth. But trouble happens as Reyna, Coach Hedge, and Nico start getting followed by Orion, the Giant Hunter. And trouble also strikes the other group when they get outwitted at the place where Gaea rises. Will the heroes fail utterly or will they end up winning?? The ending is an ultimate cliffhanger. I wish that there was at least one more chapter!!! My favorite characters were Reyna and Annabeth because they are both such good leaders and really brave. I think the message in this story is to try to save the world! If you enjoy fantasy stories you will simply LOVE this!!

I am a big fan of Percy Jackson and the Kane chronicles series. This book introduces three new characters and it is told that Percy Jacksons missing. Overall I love this book.

Percy Jackson come backs, but now is in Camp Jupiter. He has no memories and only remembers Annabeth. Hazel, and Frank also join in the series. Except now they are going on a mission to rescue the death god Thanthos.

The Mark of Athena is one of the most suspenseful book I ever read. I never could stop reading it. Four Greek demigods are visiting camp Jupiter on the Argo two (made by Leo). They visit Camp Jupiter and the two roman demigods. They also pick up Percy Jackson from camp Jupiter. They needed seven demigods to complete the prophecy of seven. They have lots of things to do. Save Hazels demi brother, close the doors of death, and find the Athena Parthenos (the Athena statue). Can the seven demigods do this?
