Included are Shadow Burns, Deadly Wrong, Ashes and Arsenic, and Once Darkness Falls.ABOUT SHADOW BURNSWhen more than a dozen people die at a retirement home, the official story is carbon monoxide poisoning.

As an agent working for the Office of Preternatural Affairs, he’s always looking for supernatural answers to deadly questions.Isobel Stonecrow agrees to help him find the truth. With her powers of necrocognition, she can speak to the dead and get the real story.But when they return to the crime scene, they find a lot more than cadavers. They find a nightmare that they can’t escape—a nightmare from Isobel’s past, which even she can’t completely remember thanks to the contract that signed away her soul.Cèsar will have to disinter Isobel’s secrets to save her. He’ll learn who Isobel used to be, what she’s done, and the price she paid…no matter how deadly the knowledge might be.ABOUT DEADLY WRONGIsobel Stonecrow’s life has an expiration date: One month, two weeks, four days, and six hours remaining.Not that she’s counting.When she signed a contract giving her soul and memories to a demon named Ander, she didn’t expect that she would ever have to face termination. But now Ander is dead and she’ll be following suit if she can’t find a way to dissolve the deal.Too bad she can’t remember anything from the time before she signed the contract.Fritz Friederling, a billionaire demon hunter who owns several businesses in Hell, isn’t ready to give up on Isobel. But she isn’t sure that working with Fritz is better than dying. She doesn’t know much about her past life, but she knows that she signed Ander’s contract for a reason—and that getting away from Fritz was a significant part of it.Escaping her contract means remembering the life that she chose to forget. And it means trusting Fritz Friederling, who Isobel fears might be the biggest danger of all…ABOUT ASHES AND ARSENICAgent Cèsar Hawke is in his element when he’s investigating magical crime.
