I wanted to spend more time with her; she was constantly in my thoughts, and right now the only thing I wanted was to lean in and kiss her. Which was, of course, disastrous for the mission, but I couldn't help it. Somewhere between that day on the beach when I'd met her for the first time and the night of the party when we'd kissed in the ocean, she had become something more than a potential target. She had, very inexplicably, become the most important thing in my life.And that terrified me.
