Coldhearted Protector by Juno Wells

He saved her from the worst fate imaginable. Now he must save her from himself.
To her friends, Sarah is the “fragile” one. The one who needs to be protected from everything. But it takes great strength to endure what she has, and the people she loves don’t even know her deepest secret: That she can recall other people’s memories just by touching them, whether she wants to or not. It’s a terrible curse, but it’s also the thing that helps her remember him.
Many years ago, Khalux saved a young human woman from a fate worse than death. But that was before. Before he was stripped of every emotion; made into a cold, calculating weapon to be wielded by the Asrai. Now he’s been given a mission to bring the empaths to As’vidan at any cost… so they can wipe the emotions of all the other Asrai, too.
One touch from Sarah sparks a shared memory, though, and Khalux is forced to face the first flicker of emotion he’s felt in years. He wants to snuff it out, to keep his place among the Asrai, but something about Sarah is too enticing. She brings out a side of him he thought long buried, and all he wants is to cherish and protect her…
Even if that means removing himself from the picture.
