Chosen By the Barbarian by Iona Strom

This alien barbarian can’t be trusted, but he’s my only hope for finding my lost friend.

Crash landing on an alien moon with four other women has become the least of my worries since setting eyes on the notorious space pirate. He’s an inmate on the loose with a hidden agenda.
I don’t want to like him, and I don’t want to be attracted to him. As we search the dangerous forest on Zune, he shows an unexpected side of himself I’m unprepared for, and mild attraction grows into an irresistible fascination that won’t be denied.

Can I find my friend without losing my heart?
