The Blood Book  The Blood Book: Tales, Confessions and Rumors of the Worlds is a novel by New York Times bestselling author Ted Dekker, along with Kevin Kaiser and Josh Olds, with additional assistance from Gregg Hart. It is a part of Dekker's mega-series, The Books of History Chronicles. The book is compiled in-universe by High Priest Ba'al, and takes place in the far future in a world known as "Other Earth". Ba'al commissions General Mustul and alchemist Grushon to study and document a variety of mythical creatures from their world, including the fearsome Shataiki bats and their interesting counterparts, the Roush. Ba'al compiles their accounts into his journal, known as a blood book. He also includes stolen journal entries from his enemy Thomas Hunter and his master, the Shataiki queen Marsuuv. It contains sketches of various creatures and locations featured in Other Earth. A certain Blood Book, though not Ba'al's, as there were more than one, also plays a significant role in the plot of "Immanuel's Veins", as the main character Toma Nicolescu uses the information contained within to defeat the villainous Vlad van Valerick. It appears that the concept of Ba'al's Blood Book was adapted after the release of "Immanuel's Veins", as it contains both new and different content than what was mentioned in "Immanuel's Veins", and is missing certain other details. A man whom Toma called Saint Thomas the Beast Hunter is implied to be the one who penned Toma's Blood Book. Ba'al's Blood Book was also mentioned briefly in Dekker's novel "Green", as it was compiled only about a year before "Green" took place. "The Blood Book" was first rumored by Dekker on his old forums sometime in 2008, before the release of "Green". There he spoke of a pair of journals, known as the "Blood Books," which would give insight into the minds of two characters from his Circle Series, presumably Thomas Hunter and an enemy. As time went on, the two books merged into a single book. In 2009, Ted released "Immanuel's Veins", in which a Blood Book plays a significant role. On his Facebook page, Ted Dekker posted suggesting that he would not publish "The Blood Book", but after much protest from his fans, he consented. In 2011, in an effort to promote his newest thriller novel, "The Priest's Graveyard", Ted began a campaign entitled "Share the Love".
