I've been a fan of Lincoln Child since I borrowed the book The Relic from one of my high school students my first year of teaching. I've since read through all the books in that series that he co-wrote with Douglas Preston, and I've moved on to the books each of them has authored on their own. In fact, I think I'm a book or two behind in the Relic or Pendergast series.
Deep Storm is a science thriller. The US goverment has found something buried under the Earth's crust in the middle of the ocean near an oil rig. Peter Crane is our main character, a former Navy medical doctor called in to this top secret mission because of his past experience in a high stress situation. People in this amazing facility are getting sick, but their symptoms don't match, and there is no sign of what could be the cause.
Turns out there is more to what they're looking for, it's an alien artifact, and one they come to find should probably be left alone. And of course, as often happens in this type of book, there is one military person who is not seeing the bad things, and plans to continue for his country at all costs. Good read.
