Sentinel Trilogy

The humans on the Sentinel Battle Station have waited 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 Royal Navy warship light years from home, the battle station may be their salvation.

After Captain Tolvern and the sentinel battle station fight off a ferocious Apex assault, Admiral Drake sends her into Hroom territory to repair the wounded HMS Blackbeard and collect a fleet of Hroom warships. 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.
