Since antiquity, a mysterious relic - the bone cartouche - has been handed down through generations, revered for its ability to protect the bearer from harm. Now the cartouche is missing, and as the restoration approaches, so too the end of the world - as humanity understands it - following which all evil and suffering will be reversed. Robert Battson finds himself experiencing vivid dreams of times long past, including explicit plans for his family, which must be carried out for things to proceed as they ought to. Is Robert mad, or is there more to his visions than meets the eye? And where is the bone cartouche? A sprawling epic spanning thousands of years, The Bone Cartouche is the last book in Peter Burke's The Promise Trilogy
