*********************************************************************************
Erika Lehmann. She is the Nazis’ top spy. Code-named Lorelei, she is the English-speaking daughter of Hitler’s old comrade and a member of the Führer’s inner circle. She is beautiful, athletic, and clever — the epitome of Aryan womanhood — and she’ll stop at nothing to accomplish her mission.
Charlie Pulaski. A down-and-out FBI agent from Chicago on his last legs, Pulaski is sent on what he is sure is a pointless wild goose chase when a garbled shortwave emission from southern Indiana is accidentally intercepted by an amateur HAM radio operator.
Axel Ryker. The Gestapo’s top henchman. Ryker is Heinrich Himmler’s top problem solver, i.e. murderer. As ruthless as he is cunning, Ryker is sent to America with a startling mission: find and kill their own spy, Erika Lehmann.
The year is 1942. In Evansville, Indiana, a Jewish metallurgist named Joseph Mayer is conducting top-secret experiments for the U.S. Navy. Life could not be better for Joe Mayer: he loves his job, and he is dating a fascinating young woman…
“One of those books where sleep doesn’t matter. The suspense builds from beginning to end.” – GoodReads.com
“Highly impressive is Whicker’s knowledge of the minutiae of spying at all levels in WW II Germany, Britain, and the USA. With its detailed descriptions, Invitation to Valhalla reminds me of Tom Clancy’s The Hunt for Red October. Whicker is especially good at portraying the vicious infighting that went on constantly among the Nazi leaders.”
–Dr. Bernard Norling, author and professor emeritus of European history, University of Notre Dame

After reading “Invitation to Valhalla” several times so as not to miss any of the minute details I then toured/photographed all the scenes in Evansville, IN. I printed hard copes for myself and son in MI to have. It is a very detailed account in photos of all the events in the book taking place in Evansville, IN. When our son came to visit we took him on a “tour” of the Evansville scenes. It made the book so much more meaningful and exciting!

So many Soldiers have come up to me and told me how much they enjoyed your book. Its a great thing when your on a deployment and something as simple as a great novel can take you away from that type of environment. There is so much detail and depth, that reading it over and over again is like the first time.

My two favorite books of 2009 were The DaVinci Code and Invitation to Valhalla. Mike, you’re a genius to bring together such extensive research into a wonderfully interesting and exciting book. I’ve read it several times and I’ve told all my friends. I want everyone to read and appreciate this book and its story as much as I have.

Great book with compelling characters, interesting setup, and unique settings. Very well researched and moves along very quickly. Couldn’t wait to get to the next chapter and was unhappy when it was over. Includes insightful look at the internal politics in the Nazi high command, fascinating account of the training program for German spies, and a thoroughly entertaining and suspenseful trip through the United States Mid-West in wartime.

Great book! I could not put it down. After reading Invitation to Valhalla and now Blood of the Reich; I really would like to see more of Erika Lehmann. What a fascinating character.
As an Evansville west sider; I truly enjoyed the references to places and landmarks. My parents often spoke of their times going to the ‘Troc’ and what a wild and woolly place it was during the war.
Soon after I read Invitation to Valhalla; my husband & I had our regular lunch at Dogtown. Due to your vivid description of espionage activities; I actually found myself glancing around for that phone! It felt that real.

I was facinated by your books. I grew up in Evansville, and my father, Ottoway Furgerson, worked at the shipyard during the time period in Invitation to Valhalla. My father was killed in the shipyard on 2/15/44. It was an accidental crushing injury. He was crushed in the yard by an electrical panel that was being moved to the LST by crane and was dropped 15 ft. crushing him. I am wondering if you happened to run across any information about this in your research of the files. My father was 49 years old and a machinist at the shipyard at the time. He only happened to be crossing the yard and stopped to talk to 2 friends. The men were treated for minor injuries and then returned to work. My father was the only one who died. Thank you so much for your wonderful books. I look forward to reading additional stories by you. Sincerely, Nell Merimee

Mary Anne: I sold a movie option for Invitation to Valhalla to a Hollywood producer about three years ago. They apparently are working on it. I’m told these movies normally take a very long time and that there are no guarantees. We’ll see what happens. Thanks for your interest. Mike

I greatly enjoyed the book.
As a Henderson native, many of the places in the book are familiar to me, and it is amazing just how many are still around. (I did hear, not so long ago, the unfortunate word that Dogtown was closed.) This is was story I had never known of before. My grandfather worked in the shipyard for a time during the war, he was a member of the Asbestos Workers Union, so there is a bit of a family connection.
I would also mention that I think it was the author’s son I had as a civics teacher in high school at Henderson County, and I seem to remeber he mentioned (more than once) his father was working on a book, though my memory of that could be off.

I thoroughly enjoyed this book. Even though I read Blood of the Reich first, the suspense of Invitation to Valhalla was not lessened. I was so enthralled by the book, my naivete took over reading the Epilogue giving me the belief the events actually occurred. Bravo!

Hi Mike – awesome book, I enjoyed it thoroughly! I also learned alot which was also fantastic.
My question is, did you publish the photo of Eric, Joe, and friends in the hotel? Is that the only real photo of Erika? Would be neat to see that photo. What a fascinating story.
Regards, Frank
