Editorial Reviews

Publishers Weekly
In the seventh addition to the Sir Cumference series, cousins Per and Radius are lost in the medieval countryside when they discover a map decorated with two hand “axes” featuring X and Y coordinates. The map promises to lead them to treasure belonging to Viking Xaxon Yellowbearyd. As Per and Radius follow the map on horseback, they discover additional X and Y coordinate clues left by Xaxon, which readers can help them locate on the large map. Outwitting a gang of bandits, Per and Radius follow the last coordinates to Xaxon’s ghost, who gives them the treasure (in the form of more maps). Neuschwander does an admirable job of injecting humor (namely, some groan-inducing puns) and action (bandits! ghosts!) into this explanation of coordinates and axes, and Geehan’s thickly worked paintings contribute some drama of their own. Ages 8–11. (Feb.)
Children's Literature - Ellen Welty
Cousins Per and Radius have become lost while out riding in the forest. To escape highway robbers, they take shelter in a house inside a hill that they have discovered. They find a map inside the house that promises to lead them to the treasure of Xaxon Yellowbearyd, the fiercest Viking warrior of all time. The map is decorated with two crossed axes marked with X and Y on the handles. There is also a message followed by two numbers that promises to lead them to a great treasure. The cousins are intrigued and decide to try to follow the message. They decide that the numbers must refer to the grid corners on the map and it takes them a few minutes to realize that the zero must refer to the house inside the hill. Once they have cracked the code, they follow the coordinates on the map to find other clues left by Yellowbearyd. The last set of coordinates leads them to an island in the middle of a lake where they encounter a ghostly Viking. The ghost gives them a chest full of maps of the entire country so they will never again be lost. This is a fun way for young readers to learn about analytical geometry although they may get tired of the puns. The last page explains the actual origin of coordinate geometry. Reviewer: Ellen Welty

    A Fan of the Sir Cumference series

    I've been reading Cindy Neuschwander's Sir C series books for years . . . own the entire series in fact. This one won't disappoint her young readers who will not only add to their mathematical knowledge, but enjoy a good adventure story (Vikings!) at the same time.
