Ninja and samurai lore come together with action and adventure to create an explosive new series perfect for fans of Rick Riordan's The Lightning Thief!

Ghost, Cormac, and Kate are not like other kids. Ghost can turn invisible, Cormac can run up walls, and Kate can talk to animals -- all abilities that make them perfect for the Black Lotus, a training school for ninjas who are sworn to protect the world from the evil samurai-run Empire. But when the Moon Sword -- a source of unimaginable power -- is stolen, the three are forced to put their new skills to the test and go back in time to sixteenth-century Japan and retrieve it.
