Sum of All Tears

After a climate-change experiment goes terribly wrong, August Madison finds herself resurrected in a frozen wasteland. With most of the world's population and food sources annihilated, depraved nomadic gangs patrol the lawless landscape as outlasters claw for survival. Amid the chaos, Graysen Marx, iron-fisted leader of the domed settlement, Liberty, emerges from the catastrophic event with his own agenda. When August crosses his path, he sees an opportunity he must exploit. She sees an evil she must destroy.

Weeks after a failed climate change experiment triggers a new Ice Age, a dangerous resistance is growing at Liberty, the Mars prototype biodome settlement in Rhode Island, after Graysen Marx is removed from power. Trying to cope with the reality of the icy new world, August and a group of survivors are forced to make a perilous journey to Boston in search of biofuel, but the lawless landscape and killing cold are more than just a breeding ground for deadly scavengers foraging for food.
