Alien Mate by Penelope Woods

Once they claim you, you become their territory.
I am Anna, a junior officer working under the command of Earth Federation. My job is to patrol the most dangerous regions of the planet. I should have planned for what happens next…
First, I lose power to my headset. My emergency lights cut out completely. Darkness surrounds the entire jungle.
And then I hear him. A sharp clicking noise comes from above my head.
His arms snake around my body. Hot breath tickles my ear, and a deep growl resonates near my neck. When the syringe hits, I know I’m done for.
I’m taken and auctioned to the highest bidder. Within minutes, all of my data is erased and systematically expunged. I no longer exist.
No one is coming to save me. And I know what happens to me next…
In darkness, he rises over me like a tidal wave.
I am abducted. I am lost to the world. But he saved me.
I am his mate.
