When Daria can not accept that her former best friend Noah committed suicide, she decides to investigate. Then she finds an ominous, ancient book in Noah's secret hiding place and inevitably falls between the lines of an ongoing eternal war of three factions, one of which is a secret society her own family has been a member of for generations. But the grimoire is not what it seems to be, and it reveals truths that completely upset Daria's world. And the threatening darkness, which her family has been fighting for generations as so-called warriors of light, shows itself quite unexpectedly in the form of two lapis-lazuli-colored eyes.
