Both of these new graphic novels in the Nickolas Flux series focus on a dramatic historic incident from the point of view of the hero, an unwitting time traveler. The frame stories are slight, but they allow the history to shine. Except for Nickolas Flux, the characters are real historical figures, and their words and actions are pretty closely based on factual details. Titanic Disaster! sees Nickolas aboard the great ship, where his concern about iceberg warnings is dismissed by the telegraph operator so as "to keep up with the number of messages to and from the families and friends of our passengers." The character of Nickolas, though not particularly compelling, does provide a kid-friendly point of view that may help readers relate to unfamiliar historical situations. Some young readers will enjoy the running gag of Nickolas returning to the present cold, wet, or with strangely long hair. "Flux Facts" throughout the text and "Flux Files" at the end of each book keep the books grounded in nonfiction, while the graphic-novel format highlights the excitement of each episode. History fans, graphic-novel enthusiasts, and any kids who like a good, dramatic story will enjoy these books.
