Galaxy Raiders: Battlestorm

The thrilling second installment in New York Times bestselling author Ian Douglas's Galaxy Raiders series.
As war rages on against the formidable Galactic Authority, Admiral Alexandra Morrigan leads a daring expeditionary fleet into the galactic frontier, searching for unlikely allies in the stars. For if humankind has any hope of survival, it will need them.
After three years of deep-space combat, Earth has been devastated by the toll of war. A crushing attack by the Galactics has triggered a new ice age, killing billions and driving survivors to the brink, and now the world's nations are breaking into factions. Some want peace, some want resistance, and a select few have joined forces with the Galactics outright.
As allies become enemies, Admiral Morrigan faces threats from within and without. While Earth's leaders consider surrender, she must choose between obedience and rebellion, retreat and resistance, to seize whatever sliver of hope humanity has left.
