In the sixth entry in the Infinity Ring series, time travelers Dak, Riq, and Sera have landed in 1943 Europe to change the outcome of WWII. To do this, the threesome must split up and travel deep into Axis territory to make sure Allied spy mission Operation Mincemeat is successful. Their efforts are complicated by the villainous Tilda, an SQ leader who has followed them from the future. As always, readers are encouraged to visit the Infinity Ring website for more historical background and games connecting this volume to the others. A solid adventure that will have fans anxiously awaiting the next d final lume.

Time travelers Dak, Riq, and Sera get closer to restoring history to its rightful chronology with each mission. After saving an important book in medieval Baghdad (Cave), they fight the Nazis--and the evil SQ organization--in World War II Europe (Enemy Lines). Although fans of this brisk-paced adventure series will enjoy both books, neither clearly separates fact and fiction.
