Phantom Pains (The Arcadia Project)

Four months ago, Millie left the Arcadia Project after losing her partner Teo to the lethal magic of an Unseelie fey countess. Now, on what's meant to be a last visit to the scene of the crime, Millie and her former boss, Caryl, encounter what seems to be Teo’s tormented ghost. One problem: according to Caryl, ghosts don’t exist.

Millie has a new life, a stressful new job, and no time to get pulled back into the Project's chaos, but she agrees to tell agents from the Project's National Headquarters her side of the ghost story. During her visit, an agent is gruesomely murdered in a way only Caryl could have accomplished. Millie knows Caryl is innocent, but the only chance she has to save her from the Project’s severe, off-the-books justice is to uncover the mystery behind incorporeal fey known as wraiths. Why has the centuries-old Project never heard of them? And how do you fight an enemy that is only seen when it wants to be seen? Millie must answer these questions not just to save Caryl, but to foil an insidious, arcane terrorist plot that would leave two worlds in ruins.
