Denmark Rising is a novel set in 1940-1945 Denmark. One reviewer described it as "A workable manual for nonviolent resistance cleverly disguised as an entertaining and intriguing novel." Walter Wink said it was one of the best books he ever read. 

Harold Confer, an author and  and a long time Quaker activist, said this about the book:

“I could hardly put it down. I started yesterday morning and finished in the wee hours today. Your descriptions of the nightmares was so real it seems it must have come from personal experience. It is a good, good book. It is a book of power, real power, spiritual power. Thank you for writing it!”

Sheri Bailey, an award winning playwright said:

"Ladies and gentlemen, please welcome the birth of a classic. In "Denmark Rising" Barry Clemson has created a remarkable and action packed story about the power of a non-violent movement used by the Danish against Hitler's Nazis. Told against the backdrop of World War II, the stories of young and old, scared and brave, Gentile and Jewish, Danish and German blend seamlessly together in a novel that offers an amazing and rich tableau of ordinary people discovering the essence of their moral center or the depth of their depravity."

The novel is intended to educate our imaginations about the potential of nonviolence in large scale conflicts. It is intended to counter our love affair with violence and to make it harder for our governments to lead us into wars. Judging from the reviews, the novel succeeds in changing the way nonviolence is viewed.
