It'll take two minds to solve this mystery...

After a seven-month tour at the edge of Jovian space, Commander Tanis Richards has come into port and she's looking forward to some much-deserved shore leave. Unfortunately, her superiors have other things in mind.

Enfield Technologies developed a new technique to pair enhanced L2 humans with AIs, and the military wants Tanis to undergo the procedure. Though she feared the worst, after meeting Darla, Tanis realizes that having an AI—especially a fabulously wealthy one—is more advantageous than she'd ever imagined.

Things go downhill as Tanis is enjoying a meal at one of the resort’s upscale restaurants. There she sees a man who should be nowhere near the posh venue—largely because she killed him a week ago.

This revelation thrusts Tanis is thrust into a shadowy conspiracy between elements within the Terran Military and the Jovians that threatens to bring down the entire Federation. The only problem is that when she gets to the bottom of it, what she finds is...none other than herself.
