SoulMatch by Drew Avera
A very well-written, quick read.
Set in the distant future, humans breed with an alien race, Daliqians, and there’s a Civil War between them when the Hybriums are wiped out. Soldier Gresham meets “angel” Coralene – who is actually his Daliqian wife – and is shown what will happen to their world. I won’t ruin the rest for you, though.
SoulMatch is offered for free on Amazon (click linky title above) so go show Drew some love. And, while you’re at it, hit his site and see what he’s up to.
