Obsidio - Amie Kaufman and Jay Kristoff

My rating: ⭐⭐⭐⭐⭐⭐

From the cover:

"Kady, Ezra, Hanna, and Nik narrowly escaped with their lives from the attacks on Heimdall station and now find themselves crammed with 2,000 refugees on the container ship, Mao. With the jump station destroyed and their resources scarce, the only option is to return to Kerenza—but who knows what they'll find seven months after the invasion? 

Meanwhile, Kady's cousin, Asha, survived the initial BeiTech assault and has joined Kerenza's ragtag underground resistance. When Rhys—an old flame from Asha's past—reappears on Kerenza, the two find themselves on opposite sides of the conflict. 

With time running out, a final battle will be waged on land and in space, heroes will fall, and hearts will be broken."

So everyone has made it this far, surviving the Phobos victims, escaping the Lincoln in the battered and almost broken Hypatia, avoiding being liquidated or shaken apart in a crazy gemina field at the Heimdall station...but where will they go from here? Without access to a wormhole or jump gate, the refugees aboard the Mao and the Hypatia are stranded in space, condemned to dying aboard those ships. Their only option is the mobile jump gate BeiTech used to attack Kerenza, so it looks like Kady and Ezra are headed home, to what they don't know. Combining the refugees from Kerenza with those from Heimdall isn't all sunshine and rainbows, though...will conflict between crews put an end to their journey before the pair can find out?

Asha, presumed dead after the refugees aboard the Copernicus, the Hypatia, and the Alexander escaped Kerenza, is alive and...not well, but surviving. It's only a matter of time before BeiTech manages to repair their jump drive, liquidates the Kerenza survivors, and makes their escape. Asha and her friends are fighting back, but when BeiTech supplies start to go missing, none of the resistance seems to know what's going on. Are their plans unraveling? Or will Asha survive to be reunited with her cousin?

I've waited for this book for so long, and it did not disappoint. Action packed, breathtaking, intense...the trilogy is complete, and it remains one of my favorite stories ever. There were gasps, there were tears, at one point I broke down sobbing...read this book. READ IT.
