Earth's Mark (Lords of Krete #2) by Rachael Slate

This is a great love story between two strong characters. Although, in this case, the man has the soft heart that is willing to bend. He does this for his people, and for the woman that he is falling in love with. He will have to overcome many obstacles, but the greatest one will be Kleo's heart. This book is well written and fits well within the series.
