Quest [EPUB ebook] 

Mankind’s greatest mystery lies in wait…Civil war rages in Ethiopia. A priest waits to die in a parched prison cell; he has not seen daylight for four decades. But then a mortar shell hits the compound, and the prisoner and his secret are free.Two reporters and a beautiful photographer save this wounded man, who tells them something too incredible to believe: the location of the Holy Grail. Thus begins an impossible quest that will pit them against murderous tribes, deadly assassins, fanatical monks, and ultimately, themselves. The Quest is a breakneck search for an ancient legend amid a dangerous jungle war — and no one’s coming out unscathed.
