*********************************************************************************
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.
