I haven't read it, or seen it discussed on this site, either.
Here's an Amazon.com
"Robert Marcum does an excellent job in his fourth novel. He is a professor at Ricks College and teaches Russian studies. This book takes an American businessman to Russia ,who gets tangled up with a package that has ties to the Imperial Tsar. It will keep you in suspense never knowing what is going to happen next. The list of characters becomes complex, enough so, that the author gives you a list in the beginning of the book as to who the characters are. It is written by an LDS author, and the main character in the book is an LDS person. But it crosses over to anyone who loves a great book!"
I believe LDS is an abbreviation for Latter-Day Saint. I wish they'd specified *which* tsar the plot is concerned with!
