Joel is fascinated by the magic of Rithmatics, but few have the gift and he is not one of them. Undaunted, he persuades Professor Fitch to teach him magical theory. Joel can't infuse his protective lines and circles with power, or bring his chalk-drawn creatures to life, but he's quick to master the underlying geometric principles. His unique skills will soon face an extraordinary test when top Rithmatist students are kidnapped from his Academy.
Since he's not a magic user, Joel appears to be safe - but he's desperate to investigate and prove himself. Then people start dying. However, can Joel really stop a killer alone? As even more students disappear, he realizes he'll need the help of Rithmatist apprentice Melody. Together, they must race to find clues before the killer notices them - and takes them out too.
The Rithmatist is a New York Times bestseller and will be enjoyed by adult and young adult readers alike. The book features illustrations by Ben McSweeney, which depict the magical elements of the novel with great elegance and insight.
