If this was going on only the characters' relationship, this would be 5+ stars. There was a build-up, banter, sexiness, and a lot of gah-don't-make-me-cry moments. But the mystery/suspense aspect imo was really average and not very thrilling. I'd have preferred that aspect to either have been missing completely or really amped up. Still Kira and Matt really are such a fantastic couple, and Kira goes on my 'fictional husbands' shelf.
