Someone has infiltrated America's future.
Eight months after disappearing, Commander Jake McCrumb has finally built the life he promised his family.
A quiet home. A new identity. A chance to leave the military behind.
Then Deputy Undersecretary Kessler arrives at his door with a message he can't ignore.
Someone has been secretly placing operatives inside the Navy's elite SEAL training pipeline. Their records have been falsified. Their backgrounds manufactured. And one of them has already completed training and been assigned to an active team.
Jake knows exactly what that means.
Someone has spent years building an asset capable of walking into America's most sensitive operations with legitimate credentials and unrestricted access.
But the deeper Jake digs, the worse the truth becomes.
The compromised SEAL candidate is only one piece of a much larger operation. Behind the falsified identities, the missing investigators, and the carefully protected network is a man named Merrick-and a project with a name Jake has never heard before.
The Cornerstone.
To uncover what it means, Jake must return to the world he thought he'd escaped, confront enemies hiding behind legitimate authority, and risk everything he sacrificed to give his family a normal life.
Because this time, the threat isn't coming from outside.
It's already inside.
