The Temple (Guardians of Destiny #4)

Synod gathers, tell them lies:

Efforts garnered in your pride
Lost beneath the granite face.
Painted Lord, stand by her side;
Repentance is the Temple's grace.

The Guardian of the Fountain of Mendhi is dying, and her successor must step up to the task. Disciplinarian Pelai is ready to accept the burden of managing the powerful magics, but the timing is inconvenient. She has one last Disciplining to perform: assigning the punishment of the three Puhon brothers--men whose lives are entwined with a prophecy of a cataclysmic demonic invasion.
 
Six months of travel have given Puhon Krais time to reflect on, regret, and repent his many mistakes. But the worst lies just ahead: defying the leadership of Mendhi means suffering harsh punishments at the hands of the Disciplinarians once he comes home. Commanded by his Goddess, the proud Painted Warrior must find the strength to submit to his destiny...or find himself, and his whole world, on the wrong side of history.
 
For in the end, one brother is destined to save humanity, one will betray humanity, and one will walk away from his humanity.
