In an isolated chateau, as far north as north goes, the baron’s doctor has died. The Interprovincial Medical Institute sends out a replacement. But when the new physician investigates the cause of death, which appears to be suicide, there’s a mystery to solve.
It seems the good doctor was hosting a parasite. Yet this should have been impossible, as the physician was already possessed – by the Institute. The Institute is here to help humanity, to cure and to cut, to cradle and protect the species from the horrors their ancestors unleashed.
For hundreds of years, it has taken root in young minds and shaped them into doctors, replacing every human practitioner of medicine. But now there’s competition. For in the baron’s icebound castle, already a pit of secrets and lies, the parasite is spreading . . .
These two enemies will make war within the battlefield of the body. Whichever wins, will humanity lose again?
