Within Ash and Stardust

Throne? In danger. Alien boyfriend? At odds with alien fiancé. A coup designed to take over both her planets? Only one of this earth girl's troubles.
Delaney wishes she were a normal teenager back on Earth with no cares but her recent graduation, her best friend, and her hot alien boyfriend. Instead she's on Xenith, a war-torn planet half a galaxy away. And on Xenith, she isn't just a regular girl anymore. She's gone from kidnapped imposter to legitimate heir to the throne. Not to mention she is, once again, engaged to Trystan, the enemy prince that turned her life upside down for a second time.
Trystan isn't all bad. Behind his poised exterior is an unwavering devotion to the people of his planet and...to her.
With her actual boyfriend finally free and planning for their return to Earth, it's getting hard to ignore that the stars are shifting for Delaney. She loves Ruckus, but she can't shake a nagging sense of responsibility to the people of Xenith. Worse, she can't seem to find it in her to take Trystan's engagement necklace off...
This choice might be easier if a war wasn't hanging over all of their heads.
Awkward love triangles aside, Ruckus, Delany, and Trystan will have to trust each other and work together to stop Trystan's father from forging an empire. He will stop at nothing to get what he wants and no one, not even his only son, is safe.
And once he's conquered Xenith...he's heading straight for Earth.
