Justin and Julia, two seemingly present-day teenagers, continue their mysterious quest through historical and spiritual history to discover who they are, what they mean to each other, and what their ultimate purpose is--one upon which countless lives depend. Their adventure deepens when they are chosen to join a special team studying an ancient prophecy: one that reveals how to rebuild Jerusalem, carry on the covenant that began with Abraham and Sarah, and something greater still--the coming of a Messiah. But nothing on their journey is ever ordinary. Their quest leads them to a kindhearted blacksmith who shares the fate of the ark of the covenant, friendships with legendary prophets, time travel alongside an archangel, and a front-row witness to the most wondrous birth in history.
