Entering his final year at Camp Half Blood, Percy Jackson and his friends are preparing for war against Chronos’ army. As the time before war ticks down, Percy must learn the secrets of Achilles and the River Styx to face Chronos in battle. Percy relies on the son of Hades, Nico D'Angelo to guide him through the Underworld so that he may find triumph in the battle.
The Last Olympian is a great ending to the Percy Jackson Series. I love how Rick Riordan brought back old characters like Nico and Hades to wrap up the story. I also enjoyed the end being a battle for the world taking place in Manhattan, New York. I would recommend this book to anyone who has read up to this point in the Percy Jackson series.
