Mother Earth: The Last Marines, Book 10 (Unabridged‪)‬

The battle lines are collapsing, and the Legion of Wolves cannot hold back the tide. Luna and Earth are both falling to the enemy, and there is little hope as the defense is pushed back on all sides.

But when Wolf learns about a race in a distant part of the galaxy that has successfully fought the vanhat to a standstill, he decides to launch an expedition to seek their help. The AI Collective has also learned about the expedition, though, and intends to kill humanity before they can find aid.

Worse, not everyone in the Governance backs Wolf, and when an enemy sees an opportunity to exploit the emperor’s weakness and strikes, can humanity stand together, or will it be lost to the darkness forever?
