He has protected humanity for thousands of years.

Until one woman makes him question the laws he has sworn to uphold.

As one of the immortal Time Walkers, Dagan has spent centuries hunting the creature determined to destroy the human race. Duty is absolute. The laws of his people are unbreakable. And loving a mortal has never been an option.

Then he meets archaeologist Reese Whittaker.

Hunted by an enemy older than history itself, Reese awakens something Dagan believed impossible. With every battle, every secret, and every stolen moment, the line between protector and forbidden lover begins to disappear.

As evil rises and the fate of humanity hangs in the balance, Dagan must choose between the oath that has defined his immortal existence... and the one woman worth risking everything to save.

Some laws were written to protect the world. Others were made to be broken.
