Faded Moon

Saros Antarian has been slowly dying since the day he restored his lover's life.
Necromancy is a curse universally feared, and its ostracized users are considered less than human. After seven years of isolation and fighting for his steadily-draining life, Saros finally tracks down his one chance to survive: Jovian's Tomb, the resting place of the first necromancer. According to myth, the tomb - a lake that only appears under the new moon, and always in a different spot - is the source of necromantic power. And if it can give power, Saros hopes it can also take power away.
When a cult bent on purging necromantic power from the world makes an attempt on Saros's life, and Saros learns that his ex-lover is their leader, he realizes that there's much more than his own life at stake. The cult intends to destroy Jovian's Tomb with the help of a resurrected god, and if Saros doesn't get to the lake first, the cult's reckless actions will tip the balance of life and death.
But every power has its temptations, and as the only one able to offset the cult's plans, Saros is left with a choice: sacrifice his power, stay out of the cult's way, and return to the society that rejected him; or strengthen his power, fight back, and let the world fear him.
