Songline - Solstice Series, #4

To stop Lemurian extinction, Julissa must conceive a child of prophecy—before Earth is destroyed in fire and flood.
One marriage. One apocalypse. No turning back.

A maligned and shamed teenager transforms into our planet's only hope for salvation.

In Telos, the city buried beneath Mount Shastina, the remnant DNA strain of the Lemurian race is at its end. On the earth's surface, world apocalypse looms. A surface-equal – a virgin with virtuous heart and pure blood – must be found to stave off extinction of the Lemurian race before life on earth is obliterated. The Lemurians believe they have found her – sixteen-year-old Julissa Grant.

With nothing left topside to hold her, the maligned and shamed Julissa makes her choice and follows the cousins into Telos.  As of yet, she is unproven and considered by many of the Lemurian council a mismatch for Aaron.  To prove otherwise, Julissa and Aaron are tested as avatars, walking Songline to see if they're compatible and capable of working together.  Burdened with three serious flaws, greed, anger, and ignorance, Julissa fails miserably with detriment to Aaron.  Julissa reluctantly agrees to return topside.  But Paragon, the leader of the Lemurians offers her a chance to redeem herself by entering the Discovery Tunnel.  Here she's challenged by a series of self-discovery tasks by Jungo, the last of the little people.  While learning singlemindedness and with time ticking down before Armageddon's Killshot is fired, will Julissa conquer her inner demons?  Or lose her place in the New World to one of her competitors?
