I just finished listening to the audiobook....

The Wheel of Darkness by Douglas Preston and Lincoln Child

Although this book was published several years ago, I was recently processing the audiobook, when I read the plot description and thought I would enjoy reading (or hearing) the book. And I did enjoy it! The authors captivated me from the beginning with the story of a mysterious Tibetan art object gone missing and the savvy and brilliant FBI agent who tracks it down. There's lots of suspense in the story, believable descriptions, and a satisfying ending. What more could you ask for? I was definitely entertained.
