The delightfully dark sequel to the gothic supernatural mystery Strange Beasts.

Six days before Samhain—the night when the veil between worlds is thinnest—Samantha Harker, daughter of Dracula’s killer, and Dr. Helena Moriarty, daughter of the famed criminal mastermind, are thrown into their next case: the mysterious disappearance of two Society field agents in Ireland. Only this time, the Royal Society is sending Jakob Van Helsing to keep an eye on them.

Sam and Hel may have solved the Paris case, but that doesn’t mean the Society trusts them. Sam has the power to slip into the minds of monsters, and Van Helsing has sworn to kill her at the first sign of corruption. And if Hel can’t prove her father’s existence, she’ll soon go down for his crimes.

Their investigation takes them from the crumbling ruins of Ireland’s untamed wilds to the occult societies of the rich and powerful. The connection between Sam and Hel is electric, but as they fall deeper into each other’s orbit, their secrets only multiply. For Hel, it’s the sins she committed when she was her father’s pawn. For Sam, it’s a plague of death omens, mysterious black feathers, and a siren song no one else can hear. And then comes a chilling revelation that is poised to shatter everything:

The agents who disappeared were each haunted by a ghost. And so, it seems, is Sam.

With characters drawn from the worlds of Dracula and Sherlock Holmes, Wayward Souls is a twisty puzzle box of a historical fantasy—perfect for fans of Genevieve Cogman, Theodora Goss, Freya Marske, T. Kingfisher, and Gail Carriger.
