Falling for the Alien Prince by Hannah Davenport

Millicent
In a post-apocalyptic world where Humanity is trying to survive, an alien species offers help—with a price tag attached. Cast back into the dark ages where women are assigned protectors, everything we fought for was destroyed with the arrival of the Andores.
Even with their rules and offer of help, I wasn’t fooled by their good looks or amazing technology. They killed my family—and now I’m out for blood.
One night, a Tizun accidently wandered upon me. Hard to look at, he impressed me with his honesty and I found that my thoughts strayed to him more and more. And then one day I wondered how I ever thought him homely.
Men and marriage are the least of my concerns. Until I’m thrust into an impossible situation: marry Jyan, the leader of the Andores, or face the consequences.

Murda
As prince of the Tizuns, I limped my ship to Earth, only to find it inhabited by the Andores. Knowing that my people will not give up until they find and rescue us, I bide my time and keep our people out of harm’s way. Even if it means following the Human rules.
While meandering through the Neutral Territory, I happened upon an ugly Human female who impressed me with her honesty and courage. I never expected to crave her company. And then one day I looked at the exotic woman and wondered how I ever thought she was ugly. When I learned of her arranged marriage, I surprised us both by offering her a way out while strengthening my human ties.
Now, we must face the consequences together.
