The Shadowless. The Dadirri Saga, #3

The Everstorm is merciless-the people who live beneath it are even worse. The earth has become a wasteland as a result of humanity's mistreatment. The sky has been dark for as long as anyone can remember, covered in an infinite roiling mass called The Everstorm. There are no trees. There is no hope. Unless, of course, you're one of the privileged who live in the protected cities beneath the domes.
In these cities, there are trees, parks full of vibrant grass, and even waterfalls-all thanks to the solar energy harvested by those who have no choice but to brave the Everstorm. Shipley Boden is a low-life working his way into the good graces of the Citizens, hoping one day to be allowed a living space beneath the protective dome. But when he stumbles upon an orphaned girl in the ruins of the past, he decides to deliver her to the nearest settlement and be done with it.
When Shipley runs afoul of violent marauders who call themselves The Red Kings, he must draw upon all the knowledge he's gained. Only now, he has a little girl to think about.
