The Four Legendary Kingdoms

I don't think it's a spoiler to say this is a crossover book that links the Jack West books to another of Reilly's amazing series. Adding that to an already incredible plot makes for a profoundly action-packed thrill-ride that keeps running strong until the very last page.

According to an author interview at the end of the book, this book helps setup the next 2 (or was it 3?) novels in the West series. That's a lot of prep work. And the next book comes out soon. Can't wait!
