Need help regarding this Egyptian Book! What does it reference to!?

Greetings, I'm studying a book called The High Priests of Memphis Second Tale of Kahumas. I would like to know if anyone has any idea if this book makes references to the book of the Dead, or if it's a book BC or AC. If it is, I'd greatly appreciate the link. When was it made, who wrote the inscriptions here and if they're from an original papyrus or what...

Thank you!
