Danger in Numbers by Heather Graham

On the edge of the Everglades, an eerie crime scene sets off an investigation that sends two agents deep into a world of corrupted faith, greed and deadly secrets. A ritualistic murder on the side of a remote road brings in the Florida state police. Special Agent Amy Larson has never seen worse, and there are indications that this killing could be just the beginning. The crime draws the attention of the FBI in the form of Special Agent Hunter Forrest, a man with insider knowledge of how violent cults operate, and a man who might never be able to escape his own past. The rural community is devastated by the death in their midst, but people know more than they are saying. As Amy and Hunter join forces, every lead takes them further into the twisted beliefs of a dangerous group that will stop at nothing to see their will done. Doomsday preppers and small-town secrets collide in this sultry, twisty page-turning thriller.

When You Can Read A Series Out Of Order And It Still Somehow Make Sense. Seriously, I don't know what to say about a book series that you can read it completely out of order- as I will have, when I read book 3, Shadow of Death - and it still actually make sense. I read Book 2, Crimson Summer, as an ARC in 2022. Going in to read Book 4, The Reaper Follows, for an ARC due in a couple of weeks, I picked up what I *thought* was Book 3 but turned out, as I found out getting ready to write this review, to be Book 1. Yet I've now already read The Reaper Follows immediately after reading this book... and yet somehow it still manages to make perfect sense to me? As in, there were no callouts that I was blatantly missing in this book to book 3? Though perhaps it was a detail thing about toy horses and island vacations, as it could in theory be possible to end each book with both of those and begin each subsequent book with both of those, but different particulars?

Regardless of all of the above, this was a fast paced compelling creepy mystery set in and around the Florida Everglades, and it worked quite well on several levels. I thought it was thoroughly enjoyable - one of *very* few books I've read of late in one sitting without really stopping. (Which could in part be due to how I was trying to squeeze both this book and The Reaper Follows in with barely 48 hrs before I left before a week long vacation, and actually finished both books within about 30 hrs of starting this one.)

Overall I thought this tale was fun, interesting, and pretty well everything I expect from an action-packed mystery/ thriller. Very much recommended.
