Sa’lok by Elin Wyn

She’s his best friend. While the war rages around them, that’s all she can be.
Or is it?

With the war against a deadly enemy coming to a head, K’ver scientist Sa’lok lives for the moments he’s assigned to work with human pilot Teisha.
She’s smart, funny and level headed. Nothing would make him risk their friendship.
But when their closest ally is betrayed, she’s thrown into unimaginable danger.
And his reaction to Teisha’s peril isn’t just wanting to protect his friend.
It’s the rage that comes with a threat to his mate.
Teisha loves three things: her sister, her sister’s kids, and speed.

After her promising career in linguistics was destroyed in the Xathi attacks, she became a pilot, helping the Alliance forces however she could.
Well, there might be another thing.
Person.
Sa’lok.
This just isn’t the time. And he probably doesn’t like her that way. Not like that.
And the end of it all can they win the battle, but still lose their hearts?
