Given how the book ends, I'm really hoping that the third book is about Kim rebuilding the trust he lost and regaining his position in the agency (possibly joined by Will). It seemed to me that Daniel was more disappointed than coldly angry with him, regardless of how he presented himself to Kim and Will. And the first book's mystery plot has basically been resolved, so there has to be something else big that Kim and/or Will is dealing with outside of their romance plotline.
