Young Abby Sherman has been summoned to Israel, where a Watcher, the Sentinel of Jerusalem, lies dying. In her last breaths, the woman tells Abby of an ancient document prophesying humanitys full-scale entry into the ongoing conflict between the armies of heaven and fallen angels.
Dylan Hatfield has strayed from the teachings he learned in The Watchers. Returned to an earthly army, he leads a secret force to reconnoiter the Afghani tunnel complex from which Osama bin Laden escaped in 2001. Abby's spiritual gifts alert her to Dylan's peril, and when she issues an Internet prayer warning on his behalf, she unwillingly sets in motion a series of events which will lead to one of America's hottest off-the-books secrets.
