Time is unraveling—betrayed by those sworn to protect it.

Rogue time stewards have defied their vows, rewriting history to seize control of what comes next. At their helm rides a shadowed figure with a blade of temporal light—sharp enough to sever timelines... and the lives entangled within them.

Seventeen-year-old Will Martelli never asked to guard the seams of time. Neither did Samantha Prescott, the enigmatic girl who's lived and lost across centuries, chasing the hidden secrets buried beneath Boston's streets. Together, they cross fractured eras—from the bloodstained cobblestones of 1770 Boston to a future locked in surveillance and silence—in search of a rupture that threatens to collapse time itself.

At the center of the conspiracy: Elias Hawke, ruthless leader of the Meridian Council, and a dark rider who hunts without end. As reality fractures and loyalty bends, Will and Sam must descend into the city's deepest shadows—where the true war for time is being fought.

If they fail, they won't just lose each other. They'll lose everything time ever held together.
