Sparked By Starlight by Sara Ivy Hill

I’m falling for the broken king. Can I heal him before he breaks my heart?

DELPHIE
The alien king is an unlikely ally, but he’s the only one who can help me find my missing friend. With a body that demands attention and a commanding presence, he could be a delicious distraction. But he’s also grumpy, bossy, and impossible to read.
Good thing I don’t have to like him. We don’t need friendship to achieve our mutual goal: find my friend as quickly as possible so I can leave his planet forever.

NIK
From the moment I met her, I knew she was meant to be mine. Her scent calls to me in a way I can’t resist.
That’s why she needs to stay far away. Because the more I’m around her, the more I want to keep her. And the longer I keep her, the more danger she’s in. From my enemies. From my planet. From me.
I broke a long time ago, and I won’t let the shards of my heart cut her to pieces.
To preserve my sanity and her safety, I’ll help her find her friend, and then I’ll help her leave…if I can bring myself to watch her walk away.
