Riveting, inspiring, and informative, Johanna's often graphic memoir, Enemy under Our Roof, is based on the author's experiences in war-torn Hengelo, the Netherlands in World War II. From nights of terror spent in the cellar during air raids to the dreaded razzias, when friends and neighbours are taken away to the camps, adolescent and adult readers will be spellbound as they are transported back to 1940's Europe.

Told through the eyes of young Cobie from ages four to nine, the narrative adopts an innocence that stands in stark contrast to the realities of war. When hordes of Nazi bombers invade the Netherlands, Cobie's peaceful, orderly world is turned upside down. Gradually she must learn to cope with fear, loss, cruelty, and despair. As she matures, she tries to make sense of the horrors of war and her Christian faith - a faith she maintains amid disillusionment and questioning.

Her most trying experience occurs when a Nazi officer billets himself in her home by force, and she is confronted with issues of hatred and forgiveness. She must battle both the enemy without and within, uncovering valuable truths in the process. Throughout the ordeal she is sustained by her older brother's sense of humour, her faithful friends, and the love and courage of her parents, who keep hope alive until the long-awaited day of liberation.
