The humans on the sentinel battle station have waited more than a decade in silence for their enemy’s return, a merciless, bird-like alien species known as Apex, who are bent on exterminating all other sentient life in the quadrant. But when a strange warship appears, the crew is thrown into chaos as one faction is desperate to communicate with the newcomers, and the other will kill to keep their mission a secret.

For the crew of HMS Blackbeard, a battered Royal Navy warship light years from home, the battle station may prove their salvation. But they must first overcome the reactionary forces on the station who would see them destroyed, and then team up with the survivors before the arrival of a menacing Apex fleet.

The first book of the new sci-fi trilogy by Wall Street Journal bestselling author Michael Wallace, The Sentinel is an exciting, action-packed space opera for both new readers and fans of the bestselling Starship Blackbeard series alike.
