(2) 4-6 When contemporary twelve-year-olds Henry, Frances, and Lukas dig up an old radio in one of their backyards, they find themselves speaking with children of the same age, and at the same location, in 1944. Alice, Lawrence, and Artie do not know the outcome of World War II, and they certainly do not understand the consequences of interfering with a timeline. Soon enough, small, seemingly heroic actions, such as stopping a fire at a beloved candy shop, start to mess with history in very serious ways. The U.S., in 2023, changes overnight to a nightmarish new reality in which the Nazis won WWII and now control the country, renamed Westfallen. The kids from the present and the past must team up to undo the colossal damage that has been done, stopping a spy and thus righting their mistakes, before Westfallen becomes a permanent reality. But that escapade is only the beginning of an adventure that will challenge readers to consider the past, the future, and the nature of history itself. Fascinating time-travel theories collide with historical fiction to set the scene for a story that is suspenseful, complex, and at times humorous. Rapid shifts between past and present might be confusing at first, but as the plot picks up, the details coalesce to form one seamless narrative. The cliffhanger ending will leave readers eager for the next installment in a projected series.
