Includes: Dead Magic, Selkie Cove, and The Wolf Witch Dead Magic: Immanuel wants nothing more than a peaceful life as a scientist, but his happiness is short-lived when his past demons refuse to go quietly. As body-snatching spirits attack and creatures rise from the dead, he fears his sanity is slipping. Disillusioned with her life, Emmeline turns to a handsome suitor who offers her a world of magic.
Something wicked is heading for London that threatens to destroy everything Emmeline and Immanuel hold dear. And it wants more than secrets. Selkie Cove: Immanuel never liked being the museum's resident seal expert, until a strange specimen arrived: part human, part seal, and a murder victim. He knows the only people who will believe him are the supernatural agents of Her Majesty's Interceptors. Upon arriving at Seolh-wiga Island, Adam and Immanuel quickly discover that what the island lacks in size, it makes up for in mysteries.
At the heart of it all is a series of disappearances, murders, and devices connected to the island's sordid history. The Wolf Witch: Since returning to England from abroad, Emmeline Jardine has managed to get a place of her own, maintain a tenuous truce with her guardians, and celebrate her new found freedom by attending as many parties as she can manage. When she receives a mysterious invitation to a country estate deep in the woods, Emmeline soon finds she is thrust into a world of werewolves, monsters, and secrets from her family's past that threaten to bring the empire to its knees.
