The Brightest Supernova

In a time set hundreds of years in the future, after the world was destroyed by atomic raids and left a nuclear wasteland. Nova Dali is the only weapons creator around, making her a hot commodity. Taken prisoner by a ruler who turns out not to be as cruel as he first appeared, Nova must make him weapons to protect her little family, not knowing she'd been swept into a dangerous romance.
Xantu Madhu, the king of the Madhus, was born the heir to the throne and wanted for nothing, but now he wants for her. An irresistible fire burns between the two of them. With enemies closer than they could ever imagine, whose own personal agenda threatens to smother their flames and rip them apart forever.
