What the Ravens Sing. The London Charismatics, #4

A world torn by war. A castle full of secrets. And the darkness of the space between the stars. In a Europe devastated by four years of conflict, a platoon of elite Italian soldiers is horrifically and mysteriously slaughtered. Strangford's arcane ability can uncover the truth behind the massacre, but a violent fate stalks him from the trenches. It's up to Lily to change its course. To succeed, she'll need the help of unlikely allies, from the brilliant police inspector who once accused Strangford of murder to an elusive spy full of dangerous secrets-and a friend that Lily once terribly betrayed.
Together, they'll follow a trail of whispers from ice-dimmed caverns to forests haunted by more than wolves where a terrible threat rises, born from the blood-soaked work of Lily's greatest enemy. Strangford's life. The outcome of the war. The future itself. All of it hangs in the balance, carried in the implacable call of a black-winged oracle over a devastated landscape of wire and mud-where Lily must open herself to the darkest potential of a power that could tear her apart.
And hope there is someone left at the end to pull her back together. Read What the Ravens Sing now and fall into the shattering conclusion of The London Charismatics series.
