" What I love about Greg Isles is that he tackles so many different subject areas and settings in his thrillers. This one begins focused on a secret government research lab. There, a select group of scientists work to create a supercomputer modeled after the human mind that will be far more powerful. Dr. Peter Tennant was appointed by the president as the ethicist on Project Trinity and is troubled by aspects of the work even before his closest friend on the project dies, supposedly of a stroke. Tennant and the other scientists on the project each exhibit neurological problems that started after a brain scan as part of the project. As he delves into his friend's death, Tennant struggles with narcoplepsy and has visions with religious aspects that he comes to believe may be memories. His psychiatrist, Rachel Weiss, tries to help, and both end up on the run across the globe from those who wish to protect Project Trinity at all costs. Tennant and Weiss are determined to stop the supercomputer before it causes the extinction of humankind.
The book's themes are large and thought-provoking. I found the characters less interesting and never was quite invested in their personal stories, other than, ironically, that of the doctor who dies at the beginning of the book. The action sequences are overall compelling, if a bit hard to believe. This is one of several books I read while recovering from surgery I had in early summer, so I wasn't feeling great and perhaps that colored my view of the book a bit. At times it just didn't hold my interest, but I finished it and found it worth the read. "
