Hidden Heroes

Camp Half-Blood has always been protected.
It just never knew by who.

For years, unseen demigods have fought in the shadows, guarding heroes who never learned their names. They weren't claimed. They weren't welcomed. They weren't meant to survive.

Now something has gone wrong.

A hidden veil has cracked. A hunter has started tracking. And for the first time, someone powerful enough to notice them is waking up.

This is the story of the ones who were never supposed to live.
