Transformers Foundations: Book 6- Annihilation

The Xorthian System is all but impassible with an increasing number of spacial rifts separating the sector from most avenues of travel beyond its boundaries. A rag-tag gathering of Cybertronians who are barely able to survive are tasked with saving every Cybertronian in the Xorthian Sector.
Bots are disappearing and some are being murdered all throughout this area of space regardless of faction or neutral standing.
It is time for old enemies to join together. Coexistence and cooperation are key if Decepticons and Autobots are to save lives.
The independent bounty hunter and freelance Autobot, Devcon, leads a small group of survivors into the greatest battle that any of them have ever faced.
They have to succeed because failure will lead to more than just the death of Cybertronians, it will lead to universal annihilation.
