Charred limbs and ashes... these are what remain of the victims in Daniel's most recent case. Thursday believes that spontaneous human combustion is what caused their death, but Daniel thinks otherwise. However, he finds himself considering Thursday's theories when an old friend is involved in the case.

Nothing fazes Thursday... except for deadlines and school essays. But something larger looms amidst the mid-term chaos. When the university experiences a series of mysterious deaths, it is up to Thursday and Daniel to find out who exactly is the cold-blooded murderer.

Thursday realises that her grand-auntie Lynn is not as strong as she once was. She decides to get a helper, much to Auntie Lyn's disapproval. But when the helper slips into what appears like a possession and Auntie Lynn is accused of abuse, Thursday embarks on investigations of her own.
