Publisher's Summary

Tom Raines and his friends are eager to return to the Pentagonal Spire to continue their training for the elite Intrasolar Forces. They're in Upper Company now, vying for spots in CamCo, but soon discover troubling changes: strict new regulations, suspicious agents in positions of power, and the revelation that the Spire is under new military control. The trainees are now cadets.
What begins as an irritating adjustment soon reveals a dangerous shift in reality. Those now in control are aligned with the corporate sponsors who have ruthless agendas. And when the military academy begins welcoming new cadets with questionable neural processors, the first step in a plan with horrifying worldwide ramifications, Tom is desperate to stop it, even if that means keeping secrets from his allies.
Then a mysterious figure, the other ghost in the machine, begins a fight against the corporations, but with methods even Tom finds shocking. And when the enemy comes for Tom, how much can Tom endure in the battle to save himself? He must decide if he can still fight when the odds of success seem to be sliding from his grip.
In this exhilarating, explosive, and heart-rending conclusion to the Insignia trilogy, Catalyst brings Tom and his intelligent, passionate, and brave young friends stunning tests and dangerous confrontations, and through to an impossible future they could never have predicted.

What an Ending!

Any additional comments?

Catalyst is a fitting closure to the Insignia Trilogy. Everything set up in the first two books, Insignia and Vortex, comes to a head in this book, and Kincaid reveals her hand one card at a time to unfold the master plot that harkens all the way back to book one. It's a masterful accomplishment, and the whole of this book was satisfying to me. Seeing the final growth of Tom, Vikram, Yuri, Wyatt, and the other characters is spectacular. There are still wonderful throwbacks to the beginning of Insignia, in the continued evolution of the gang's inside jokes. Even those jokes, as before, play important roles in the narrative. Kincaid has really demonstrated a deep understanding of character, plot, and storytelling in this final chapter of the trilogy.

I feel like every promise Kincaid made in the beginning has been fulfilled. There aren't any loose ends left untied for me, even ones that were left in book one that I thought were no longer important to the setting and characters. No, Kincaid has thought of everything, and it left me with a feeling of complete gratification. This is a fully complete series, a work done to perfection. Bravo!

I loved the story , this was a wonderful conclusion, it had everything. I must say though that the narrator Lincoln Hoppe made this book even better. He effortlessly switched between accents convincingly, his female voices were not overdone and he breathed the perfect amount of emotion into every single word, it was brilliant!
