Preston and Child are back with the third? fourth? of the Gideon Crew series.
I didn't read the first few because I wanted to get to the nitty gritty of the encounter and attempted destruction of the creature.
The authors do a good job of making this a stand-alone book, with enough references to the previous events that you get backstory to understand their angst, stress (beyond dealing with a sea creature), and what's at stake, without rewriting the whole series. The creature's description is well done to provide detail and plausible interaction.
If you enjoy creature books, like Alien and Meg, and want an easy read (with a sprinkle of gory details), you might enjoy this trip to the bottom of the ocean.
