My eyes filled with sudden unexpected tears. I put my hands over my mouth to hold in the sob that wanted to come out. I didn't want to wake Nate up, didn't want him to see me crying. But I cried, all right. I sat there at my desk and cried for her, for me, for both of us, for all of us. I can't remember hurting any more ever in my life than I did then. Hearts are tough, she said, most times hearts don't break, and I'm sure that's right . . . but what about then? What about who we were then? What about hearts in Atlantis?
