It's Viking-infested Paris, 885, in this second book by a second author in the Infinity Ring series (James Dashner's Mutiny in Time, 2012). As self-identified science and history geeks Sera and Dak ( we must be dealing with some sort of hidden variable aspect to the quantum entanglement and every modern-day European monarch is descended from Bill Helm the Vanquisher, respectively) travel through time with their linguist friend, Riq, to save the world from a still-mysterious evil organization. Many history-loving kids will be sucked in, while others will be hooked by the accompanying full-color poster-map (unseen) and corresponding 3-D online game.--Medlar, Andrew Copyright 2010 Booklist
