Blood and Hope - Battalion 1, #5

With the lives of billions of people in jeopardy, Captain Corban Rhodes and his team of super soldiers are facing down unstoppable odds with no way to turn the tide. As battle after battle turns against the him, Rhodes must find one tiny scrap of hope in a landscape of death and destruction. Could humanity's darkest hour be the moment when Rhodes finally discovers what it really means to be human-and to win back a little of what the Battalion 1 project took from him-including his own humanity?With those he most cares about under fire and with no way to save them, Rhodes must grasp at any lifeline to find the key to unlock the mystery of the Masks and try one last, hopeless time to shut them down for good.
It just might cost him everything in the process, including his own life. Warning: This is good old-fashioned, high-octane action adventure sci-fi. If hard science is your thing, you'll probably be disappointed, but if you're looking for a non-stop rollercoaster ride of danger, space action, and ass-kicking adventure, this is for you.
