Demon Heart — David Crane

Naoko Kitamura is one of the toughest and best cops on the police force in Osaka, Japan. However, her human appearance hides a dark secret that must be hidden from humans. Naoko is a demon hybrid, a descendant of a demon and a samurai. Forced to awaken her terrifying potential as a result of a brutal attack, she tries to understand her role as a creature of two worlds.

Struggling to uphold her mother's legacy as defender of Japan against evil, she faces human and nonhuman enemies determined to alter her country's destiny. Her powers are both a blessing and a curse, for, by being extraordinary, Naoko can never live an ordinary life. For her, the road to victory will be written in blood.
