All 16-year-old Connor is trying to do is avoid his ex-best friend when he stumbles upon a trapdoor to a secret chamber under his school. But when Sally Rodgers breaks into the same secret chamber looking for an ancient being, things take an unexpected turn . . . and Connor's life will never be the same again.
Along with the mysterious Sally and, later on, his new friend Locky, Connor discovers the Monuments - gods who have been buried for generations - who created the world and hid themselves away from humanity to keep everyone safe. But now they're exposed and vulnerable, and Connor isn't sure who, himself included, can be trusted with the knowledge and the power these gods have.
