Junisphere Rain (Warlight’s Atonement) Book 2:. Junisphere Rain, #2

The lie that held Junisphere in a chokehold for eighteen years has been shattered on the summit of Swallow Hill, but the truth has not brought rain. It has unleashed a storm. His personal vengeance complete, Eehaa Borachoo now carries a new, more profound burden. Guided by the last Dragon Speaker, he must embark on a shamanic quest to the planet's very core-to the legendary Caldera of Creation. His mission: to forge a new key that can awaken the last dormant dragons and heal a dying world.
But he is not alone. An assassin from a paradise kingdom stalks his every move, sent by a serpent-king desperate to protect the original sin. In the North, the Obsidian Fortress is at war with itself. Princess SheeHaa Moondid, now a reluctant stateswoman, has formed a fragile alliance with the weary High General. Together, they must fight a shadow war against a treasonous admiral who seeks to seize power by rotting the North from within.
As they point the might of their fleet towards their true enemy, the manipulative King Bellaheart, they are undermined by a new wild card: SheeHaa's own father, the disgraced High Lord Warlight, who has begun a strange and obsessive quest of his own from his isolated spire. As all factions race towards ancient sources of unimaginable power, the lines between hero, villain, and penitent blur. On a world where the only thing more dangerous than the original lie is the chaotic truth, can a handful of fractured heroes restore the sky before the planet breathes its last?
