Welcome Back to the World of The Grid. Where heroic bad-asses looking for a second chance fight a war among us in the shadows. Marcus De Monte was born in Hell, both literally and figuratively. Birthed by a demon, sired by a human and considered a failure from the moment he took his first breath. Nothing more than fuel for the Hell fires. Allowed to live by Lucifer himself, he became determined to reach the top of the food chain by becoming an elite assassin in the Dark Lord’s army. After reaching that bloody, hard-won goal he chose a path not ordered by Hell—one leading to love. But that love became doomed the moment it bloomed. Fueled by rage of its loss, his payment was the shameful duty of bodyguard to the Keeper of Madness – Reno Sundown and his family. But denied destiny has fatal consequences. The one chance Marcus had of being reunited with the one he loved vaporized. But destiny has a way of masking itself until its time, and Marcus is no exception. Will the newest Keeper find his heartbeat, even when it beats quietly from the past? Or has Hell played the ultimate trick on Marcus… and the past to burn love to ash once more? And the dark power of Murder has a new host, and it has its own scores to settle.
