The Secret of the Dragon s Teeth continues the adventures of Gavin Kane, Emily Scott, and Bunty Digby, sixteen-year-olds who struggle with their daily lives in England during the pivotal year of 1944. Cornwall is now an armed camp, with thousands of Americans and Canadians, as well as men from throughout the occupied countries, all training and preparing for the invasion of the European continent. The war has reached a brutal climax and the Allies now have the upper hand. In Nazi Germany, however, Heinrich Himmler is far from admitting defeat, as he prepares to unleash whatever horror he can devise to delay the inevitable.
