A new president. A nation watching. A promise he must keep.

He survived assassination, corruption, and a deep state conspiracy. Now comes the hardest part.

The Oval Office was supposed to be the victory. But governing a fractured nation ? with hollowed institutions, a suspicious Congress, and enemies still lurking inside the machinery of power ? is a war David Shepherd never trained for.

As President, David must rebuild what corruption destroyed. But not everyone wants America healed.

Sanctum may be exposed, but its roots run deep ? and the allies David needs most may be the ones he trusts least.

His faith is tested not by bullets, but by compromise. Not by assassins, but by the slow, grinding weight of power.

Can a man of God govern without losing his soul?

Will David find a way to lead a divided nation toward renewal ? or will the Oval Office do what Sanctum never could?

Will the very power he fought so hard to redeem begin to change the man who holds it?

The battle for the nation continues. The battle for the man has just begun.

Mandate is the fourth book in this fast-paced, action-packed Christian thriller series. Think David Baldacci, James Patterson, Mark Dawson, and Lee Child meet Colleen Coble and Lynette Eason. This is a modern-day re-telling of the King David story. The establishment will stop at nothing to stop David Shepherd's rise to power ? and assassination isn't off the table.
