Sentinel Trilogy Books

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.

After Captain Tolvern and the sentinel battle station fight off a ferocious Apex assault, Admiral Drake sends her into Hroom territory to repair her wounded warship and collect a fleet of Hroom sloops. While Drake probes the deep void searching for the main enemy force, Tolvern and the Hroom spaceyards are assaulted by a massive Apex battleship that intends to harvest Hroom and human alike for its bloody rituals.

A desperate alliance of human and Hroom factions gather to defeat Apex, a brutal alien menace who has vowed to exterminate all civilized races from the sector. The final book of the Sentinel Trilogy.
