N. K. Jemisin - The Killing Moon (Dreamblood #1, epub) [j_ray]

In the ancient city-state of Gujaareh, peace is the only law. Upon its
rooftops and amongst the shadows of its cobbled streets wait the
Gatherers - the keepers of this peace. Priests of the dream-goddess,
their duty is to harvest the magic of the sleeping mind and use it to
heal, soothe . . . and kill those judged corrupt.

But when a conspiracy blooms within Gujaareh's great temple, Ehiru - the
most famous of the city's Gatherers - must question everything he knows.
Someone, or something, is murdering dreamers in the goddess' name,
stalking its prey both in Gujaareh's alleys and the realm of dreams.
Ehiru must now protect the woman he was sent to kill - or watch the city
be devoured by war and forbidden magic.
