Kor’ven by Alana Serra, Juno Wells

For every action, there is an equal and opposite reaction… especially when two strong-willed scientists collide.

Addison Monroe has dedicated her life to studying the Karuvar, striving to bridge the gap between their longevity and that of her fellows humans. Work has always been her focus, and she refuses to let love come before scientific achievement the way her mother once did.
But when she’s unable to place a life-sustaining implant in the first child born to human and Karuvar, Addison is forced to rely on the expertise of the most arrogant, infuriating Karuvar she’s ever met… who also happens to be her mate.

Kor’ven is no stranger to the pitfalls of Karuvar science, and he has spent his life trying to make up for the costly mistakes of the past. Once involved in a flagship project to manipulate Karuvar genes, he’s spent every waking hour trying to prove that the Karuvar’s greatest strength–their ability to adapt–may be slowly killing them.
The last thing he needs is the passionate, driven human scientist he so desperately wants to claim as his own.
The force between them is magnetic, and collision is inevitable. But with time running out, Addison is forced to make a desperate choice between the future of Karuvar and humans… and her future with Kor’ven.
