The Secret King – Lethao by Dawn Chapman

Kendro, King of the Aonise, can do nothing to prevent their sun from collapsing, consuming their home planet Letháo in a single fiery blast. Running out of time and options, he evacuates the entire population, setting off into the unknown galaxy in four crowded ships. Under constant danger from their ancient enemy, the Zefron, treasonous dissent seeps into his inner circle. Threatened inside and out, Kendro struggles with whom to trust, until a mysterious vision finally brings hope to the distraught King. A new home awaits the Aonise, if Kendro can only unite them long enough to survive the journey.
