Beyond the Southern Dunes. Sands of Nanterac, #2

Beyond the desert dwell monsters far greater than any demon that hunts in the dunes. Dana, last seer of Nanterac, has reclaimed her city and found love. But when her partner Philyre is poisoned by demon's blood, Dana only has sixteen days to save her. A stranger's vision points her south, beyond the demon-infested sands, where hope for a cure still burns. Funanya and Askaran agree to leave their hard-won peace to aid her, but disaster strikes: the Grand Archon of Berinta, a seer stronger than any in living memory, has come for them.
Askaran is captured while Dana and the others are sold into slavery. Torn from her friends, Dana must unravel the web of possible futures before Askaran succumbs to his demon's call. or Philyre runs out of time. Her desperate search drags her centuries into the past and reveals the truth behind her people's presence on Nanterac, answers she wishes she'd never found. If the last seer falls, so falls Nanterac.
