Sins of the Past - Rogues of Magic Series, #6

The past will always come back to haunt you. When her cousin calls her begging for help, Ann and her band of rogues rush in to save her before it's too late. Upon arriving in the realm of Asral, Ann is shocked to discover Riven's lands being ravaged by an army of powerful warriors. The Jer Oza are an elite fighting squad sent by Lord Arwan, an elder, and someone connected to fellow rogue, Jax. In order to defeat their enemy, Jax must face the demons of his own past and Ann must come face-to-face with the very people who had her family killed and took her throne six years earlier.
But the elders are not to be trifled with. Will the rogues defeat their greatest enemy yet?
