Book 2 of the Tomo series, Bad Heir Day, finds Hana in worlds of trouble---two worlds, to be exact. At school she faces suspension when Rachel and Traci, classmates who dislike her just because she's Japanese, make it look like she's cheating on a test. While she tries to defend her reputation, another threat emerges, as animal-like ninjas from Argon Falls strike again---this time with reinforcements. Though badly outnumbered, Hana is not alone, and she is not unarmed. Her grandfather's goofy, unmannered pet proves himself a worthy ally, and for the first time Hana wields the mighty Spirit Sword. Hana learns about the nature of truth as she battles lies and as she discovers more about this strange being called Tomo, the mysterious weapon he's given her, and the role she's been called to play. Truth is a powerful thing---but is it enough to help her prevail?
