Beneath the Copper Sky - The Nightshine Saga, #1

Amione returns to Titan for her father's funeral. His death is ruled an accident by Titan Officials, but clues left by her father tell a very different story. An unusual seedling, a picture, and a data crystal lead her down a dangerous path, one that will reveal her father's killer. The only way to know the truth is to go to the surface. With the help of her devoted friend, estranged mother, an attractive stranger, and a shadow entity that takes itself a little too seriously, she just might survive.
But the cost will be higher than she could ever imagaine, and change her in ways that are both wonderous and terrifying.
