Hero’s End by J. C. Cassels

Given the choice between Love and Duty, which does one sacrifice for the other?

When a former lover with a score to settle nearly brings Blade Devon’s charmed life to an end, he seeks refuge and some time to lick his wounds with an old friend… leaving the woman he loves behind.

Bo Barron is no frail flower, despite her masquerade as Blade’s Joy Babe Mistress. She straps on her sidearm and goes off alone to track her missing father, kicking off a search that stretches across the galaxy – from the lair of the gruesome Rex, a clone with a taste for sentient biomatter, to Rogue’s Cross, the most dangerous space station in the outer Commonwealth.

Someone close to her doesn’t want Bo’s father found. To make matters worse, the First Sector Overlord orders Blade’s holofeature career over and Bo out of his life for good.

Surrounded by betrayal, Bo and Blade turn to each other, but the secrets he protects threaten to tear them apart
