When They Saw (When They Came, #2) by Kody Boye

I never expected to be abducted. But here I am, standing onboard Their ship, facing Them down for the first time in my life, seeing the true face of the Earth’s invaders from another world.

My task is simple: to act as Earth’s emissary and negotiate peace. But it is far more complicated than it seems. I know nothing of politics, and even little of persuasion, but I have no choice. I must do this to keep my friends, and my world, safe. I cannot afford to fail humanity.
