Amazon.com description: Product Description: I Was an Eighth Grade Ninja, book 1 of the Tomo series, introduces Hana, a thirteen-year-old Japanese orphan struggling to adjust to life in San Francisco. Hana tries to feel at home in her grandfather's house and does her best to fit in at her new school, but the only time things seem normal to her is when she's honing her skills in her grandfather's dojo, the studio where he teaches martial arts. And just as she's learning to cope with one strange new world, Hana is forced to deal with another. Animal-like warriors from a different dimension invade her grandfather's home, and Hana must use all her training to protect the only family she has left. When the secret of a mighty weapon is revealed, Hana discovers she is not who she thought she was---nor is Tomo, her grandfather's strange little pet.
