Seraphim: A Zoë Martinique Investigation (Zoë Martinique Investigations) (Volume 7)

This time Zoë's working for the Seraphim, and the benefits are life, or death. A forgotten message reveals the location of a Faerie relic, an instrument forged in the infamous Bulwark, the very same relic the Phantasm employed Zoë to find in locating the missing Detective Joe Halloran. But in order to save him, Zoë must beat the clock to find the Grimoire's missing sections for the Seraphim. But will she succeed when she finds herself once again pitted against the Revenant Coterie, the Society of Ishmael and the grand-children of Echidna.
