My thoughts (lvh): COLD PURSUIT may be the sixth book in the series, but it easily stands alome. Alex and Sam are the two members of the team featured in this story, but wow! They had a major job and plenty of excitement.
As per Ms. Sleeman's style, you think you have it figured out who-dun-it, but there is a twist that you never saw coming. This is NOT formula romantic suspense.
If you like romantic suspense, you will love the Cold Harbor series.
