Cassandra Clare said this quote

He dropped his voice, so low that Tessa wasn’t sure if what he said next was real or part of the dream darkness rising to claim her, though shefought against it.“I’ve never minded it,” he went on. “Being lost, that is. I had always thought one could not be truly lost if one knew one’s own heart. But I fear I maybe lost without knowing yours.” He closed his eyes as if he were bone-weary, and she saw how thin his eyelids were, like parchment paper, andhow tired he looked. “Wo ai ni, Tessa,” he whispered. “Wo bu xiang shi qu ni.”She knew, without knowing how she knew, what the words meant.I love you.And I don’t want to lose you.
