Wakanreo Series by Carmen Webster Buxton

In ALIEN BONDS, two lives are changed in an instant. Industrial chemist Dina Bellaire travels all the way to the planet Wakanreo to advance her career. Her carefully planned life goes up in flames the second she meets Kuaron Du, a Wakanrean who makes his living singing ancient songs in a dead language. Both of them know they can’t go back to the way they were before they met. They just have to convince the rest of the universe that what happened to them is real.

Yulayan Bellaire has grown up knowing she's different. Her mother is human but her father is Wakanrean. No matter how Wakanrean she looks, no matter how much she tries to blend into Wakanrean society, her human half is still there. Still, Yulayan expects to mate as all Wakanreans mate, totally by chance, as soon as she comes near a man with compatible pheromones... moreYulayan Bellaire has grown up knowing she's different. Her mother is human but her father is Wakanrean. No matter how Wakanrean she looks, no matter how much she tries to blend into Wakanrean society, her human half is still there. Still, Yulayan expects to mate as all Wakanreans mate, totally by chance, as soon as she comes near a man with compatible pheromones. And then one day she meets Kamuhi Hailoaka, a physicist from Terra who finds her unique genetic combination appealing, and she discovers that her human half is more in control than she had thought possible. less

Kamuhi Hailoaka’s desire to see other worlds led him to Wakanreo, the only world in the galaxy where the dominant species mates for life. Kamuhi met and married half-human, half-Wakanrean Yulayan Bellaire. After the Third Confederation of Planets rescued Yulayan from Inchauro Perduay, the man she found herself mated to, Kamuhi enlisted in ThreeCon. Now constrained by their rules and regulations, he and Yulayan work at being married and raising a child... moreKamuhi Hailoaka’s desire to see other worlds led him to Wakanreo, the only world in the galaxy where the dominant species mates for life.

After the Third Confederation of Planets rescued Yulayan from Inchauro Perduay, the man she found herself mated to, Kamuhi enlisted in ThreeCon. Now constrained by their rules and regulations, he and Yulayan work at being married and raising a child. Kamuhi has always excelled at academic subjects, but simultaneously navigating the pitfalls of bureaucracy, interspecies politics, marriage, and fatherhood at the same time is more of a challenge. Once he is assigned back to Wakanreo, the challenge becomes not only harder but more dangerous. For one thing, Inchauro Perduay still sees Yulayan as his mate. less
