We're excited to share a description of Red Samurai:
"Thirteen-year-old Roxy Ran is in Year Seven, has a secret crush she is desperate to keep secret, an older sister who drives her crazy - plus the school bully to deal with. Roxy could be any girl… but she’s not. Roxy Ran is the White Warrior, an awesome invisible ninja with fighting and flying powers; and the bullies she deals with are Samurai assassins.
Roxy’s sister Elecktra has always been a great magician, but when she shows off her magic tricks at school the town of Lanternwood begins to transform. The streets take on a sense of Samurai and the ninjas are no longer safe.
There is an enemy lurking and it soon becomes clear that the White Warrior is about to meet her match."
