Query: Entertaining book... but not Preston & Child's best

If you are already a fan of Douglas Preston and Lincoln Child, then you will like this book, which is another one featuring the popular character of Agent Pendergast.I personally did not prefer it as much as others because no other recurring characters (Laura Hayward, Constance, Nora Kelly, Smithback, Nora Green, etc) appear, and it is a standalone book. The character of Corrie acts as a pretty entertaining sidekick and interesting character, though I would be surprised to see her reappear in another novel of theirs.This book also one of their most gruesome in my opinion.If you are just starting to read Preston & Child, I would not start here. Maybe try Cabinet of Curiosities, which I think is one of their best books.
