Perfect for you if...

You loved the first two Heroes of Olympus books and need to know what happens when the Greek and Roman camps finally meet.
You're drawn to ensemble casts where characters have to overcome mutual distrust to survive something bigger than themselves.
You want action, mythology, and genuine stakes without getting bogged down in heavy adult themes.

Maybe not for you if...

You prefer standalone books or stories that resolve neatly in one volume, as this is book three of a seven-book series.
You've never read any Rick Riordan Percy Jackson books and don't want to start with the backstory already in motion.
You're looking for dark or gritty content. This is upper-middle-grade adventure with humour and heart.

About this book

The third book in the Heroes of Olympus series, The Mark of Athena reunites Percy, Hazel, and Frank from Camp Jupiter with Jason, Piper, and Leo. Together, the six demigods must work to defeat the giants released by Gaea, the Earth Mother. However, the Prophecy of Seven calls for seven heroes, leaving the question of who will complete it unanswered. The group must cooperate despite their Greek and Roman backgrounds and sail together to an ancient land to find the Doors of Death. Much of what the prophecy demands remains unclear. With old and new allies joining forces, a remarkable ship, powerful enemies, and an unfamiliar setting, the demigods face another adventure in their ongoing quest.
