The third book in the bestselling spin off series from Percy Jackson and the Olympians, featuring the original hero – now in a brand-new look!

Seven Heroes. One Prophecy. Destiny Calls.

After spending months apart, finally demigods Percy and Annabeth are reunited, along with their friends – Frank, Hazel, Jason, Piper and Leo. Seven heroes bound together by a terrifying prophecy that threatens them all.

Now the heroes must work together to retrieve the Athena Parthenos – a sacred statue of the Greek goddess – only, it’s closely guarded by an old enemy. Failure though means putting all of humanity at risk.

They’ve already saved the world once. . . twice shouldn’t be a problem, right?
