A Goddess of Life & Dawn (Pine Hollow Series) by K. M. Moronova

Once upon a time, there were two Rhythm Gods: one of brilliance and one of darkness. But there was much more to the realms than the two gods alone could provide, so the Maker created a third, unknowingly unbalancing the Rhythm and setting the realms on a path of suffering. The God of War has stolen that which I hold dearest. Though I am reunited with my beloved gods, a hole remains and my heart is in shambles. Together we must look to the past to preserve the future, for if we cannot restore the Rhythm, the realms will crumble.
