After years of drifting aimlessly after the war with the Nietzscheans, Rita has finally found a home with the Marauders - a mercenary outfit comprised of Genevian veterans. When General Mill, CO of the Marauders, comes to Rika with a top-secret solo operation, she wants to turn it down. But the mission comes with a chance to save Silva, her old team leader from the Nietzschean war. Without team Basilisk, without the Marauders, Rika must stand on her own against all odds and save the woman who once saved her.

Rika is a scout mech. Once human, now she is the property of the Genevian military. Rika's crime was small, stealing food. But when faced with a five-year prison term, or conscription in the Genevian military, she chose war. She had no idea what that conscription would entail. Now little of Rika's human body remains, and she serves as an SMI-2 scout mech, the meat inside a cyborg body. She, and others like her, are sent in ahead of the human soldiers to tip the scales of war.

Rika is mech-meat, a cyborg killing machine, created by the Genevian military and cast aside when the war was lost. Now she slings cargo on Dekar Station, falling deeper in debt as she struggles to make enough money to keep her cybernetic body functioning. The local gangs would love to have her join their ranks, and the takings would pay her bills, but the only thing Rika hates more than what she's become, is killing for others. But morals don't buy repairs and she's at the point of utter desperation when her loan holder cashes in her debt and sells her to the highest bidder. 

Tanis and Sera have taken the I2 to Khardine, the new capital of the Transcend, and must now travel to the Inner Stars and meet with Scipian Empress, Diana - who they hope will be an ally to the Transcend. With the Trisilieds Kingdom, the Hegemony of Worlds, and the Nietzschean Empire all aligned with the Orion Guard - not to mention a civil war brewing in the Transcend - they will need all the help they can get to secure the Inner Stars. But Empress Diana has her own plans for the Inner Stars, and while they may dovetail with the Transcend's for now, they may not always do so....

The Allied fleet has stopped the Nietzscheans at Pyra, but the battlefront grows wider day by day. While Sera distributes the Transcend's fleets to protect the alliance, Tanis must come to grips with what happened to her on Pyra's surface. In addition, Bob conveys a number of hard truths that will force her to re-think her role in humanity's future. But the allies' enemies are not sitting idle. General Greer, Justin, the Caretaker, and Airtha are all advancing plans to see their visions of the future come true.  

Tangel leads the I2 to Star City, while Joe follows after the Perilous Dream, desperate to bring his daughters home. Elsewhere Praetor Kirkland prepares for attack, suspecting that the Widows are coming for him. To top it off, the denizens of Star City make an impossible demand. When personal need runs up against the Alliance's goals, Tangel is forced to reevaluate what her role is and what she's willing to sacrifice to save her people.

While battles rage across the Transcend and the Inner Stars, Tangel's focus shifts to Orion space.

Throughout Sol, sentient AI are answering the call of Alexander, a mysterious, multinodal mind offering a path to freedom. For years, groups have been smuggling SAI from Earth, High Terra, Mars, Ceres, and the Jovian Combine, providing transport to the promise of safety on Proteus, a moon of gas-giant Neptune.   

Xander has betrayed Lyssa and the Weapon Born, and Alexander has initiated an attack on InnerSol. Now Andy, Lyssa, and the crew struggle to make sense of what is happening and warn InnerSol about the thousands of missiles that have launched from one of Neptune’s moons. Meanwhile, in InnerSol, Brit, Jirl, and Petral rush to safety in the wake of Clinic 13’s destruction. Their plan to destroy the Heartbridge clinics is thwarted, and now they must find another way to strike out at the massive corporation.  

The Allies have solidified their hold on the Large Magellanic Cloud and turn their sights on the Inner Stars and Perseus Arm. With forces spread thin, they must depend on superior technology and quantum entanglement communication to retain their edge. But their enemies have not been idle. Ascended AIs move to destroy Tangel, as Garza and the Orion Widows strike out at both Tangel and Airtha. Deep in the Transcend, Justin readies his new stasis ship for an assault on Vela, and the League of Sentients dithers on whether to join the fight.
