Drift Would by Cynthia Sax

Drift is one of the best pilots in existence, and he has been assigned a perilous mission.

The G Model cyborg must fly to a distant planet, locate the sector-destroying superweapon the enemy is projected to be developing there, and obliterate that threat to the universe.
When Drift arrives at his destination and meets with an informant, he’s distracted by a mysterious human female seated in the shadows. She’s Drift’s genetic match, and she is the one being he’s destined to care for, claim, and protect.
