The Rifter's Covenant: Exordium 4. Exordium, #4

In this rewritten fourth volume of the series Exordium, the Panarchy is in shambles, coalescing at the military base Ares. Brandon has inherited not only this political tinderbox, but also must face the escalating threat from the invading Dol'jharians and their Rifter allies before they can power up the ancient artifact they call the Suneater. But moving with secret, deadly precision against Brandon is a traitor who will do anything for power.
Meanwhile Brandon has fallen in love, but everyone thinks it's with the wrong person. Space battles, political in-fighting, and personal struggles ramp up the stakes in this penultimate volume in the five book Exordium series.
