Beast and the Harlot (Neophyte Series 3)

Three months have passed since Michael's return from the depths of Hell. The Calling has brought hundreds to the Sanctuary, as the Neophytes build an army of the faithful. Each Elder now finds themselves teaching the masses, learning all there is to know about the beyond, and the grand agenda that awaits each and every one of them.
The destruction of Belial's realm had unleashed his demonic minions upon the earth. Michael, Urielle and Samael spend each waking moment traveling the earth, dealing with the global possession pandemic, as the mass of Catholic exorcists find themselves overwhelmed. Only when they learn of the specifics of the Antichrist's prophetic rise does Michael abandon the crusade to focus and complete his training.
A vital piece of the Infernal Machine (a device with the power to merge the realms and bring Hell to earth) is located in the most curious and heavily protected places on earth. In order to keep this weapon from the grasp of Lucifer, the Neophytes will need the help of an insider. Father Theron must rise to the occasion in order to infiltrate the Vatican.
An epic standoff of good vs. evil awaits in the so-called Holy City, where demons lurk in the shadows, and the divine find themselves powerless. In order to be successful, Michael must put his trust in a long lost brother and his wayward cousin, as the fate of the world now dangles on the thinnest of threads.
Beast and the Harlot is the third installment of the Neophyte Saga, merging together First of the Fallen (Book one) Order of the Golden Dawn (Book two) and Knock Three Times (A demonic installment outside the series.) Be warned, that in order to follow this installment, you must read at least the first two, though K3T will fill in a lot of the blanks.
