They call him the Black Widow.

Diea is a Gemini soldier, a special ops marine trained to work more closely with one partner than any other. Through the nanotech in their veins, a Gemini pair can communicate over any distance, see and hear what the other experiences, and it's been said when one partner is killed, the other will fall dead on the spot.

But the Black Widow has outlived two partners. And counting.

Phade has just transferred from Taurus to Gemini, and he's not intimidated by Deia's reputation. Phade knows better than anyone that the image people see is just a mask for what has been broken underneath. Even the hardcore have to let their guard down when the nanotech shares every heartbeat.
