The Last Olympian by Rick Riordan is the final installment in the Percy Jackson and the Olympians series. In this book, we will witness the second Titan War and we will discover the Great Prophecy that will determine if Olympus raze. To prepare for this battle, Percy will risk his life before the battle even begins by bathing in the River Styx like Achilles had done millenia before to become invulnerable in all but one place. Then, if that wasn’t enough going on for Percy, he will choose between Annabeth and Rachel to be his girlfriend. I recommend this book to grades 3-5.
