City of Blind Angels — Jacqueline Pearce

Revinport. Ancient Indlayan city of commerce and
trade. Home of the Cathedral of All Indlay, where monuments to the mighty Seraphim turn their eyes forever away from the wickedness of Man.
A city besieged by savage, random nighttime attacks that leave their victims torn to shreds.

The Myar. A proud, desert-dwelling people- shapeshifters, fierce warriors and adept in the ways of magic. Through centuries of war and enmity, the blood of many an unwitting Indlayan citizen has been tainted by that alien strain.

Illeana Grey. Ex convent-girl, small-time scrivener. Cousin to the mercenary Reahla, a woman convinced that Indlay is being infiltrated and occupied by stealth. Is Reahla's tale reality or madness? Pursued by a sinister doctor with his own twisted agenda and protected only by
Reahla's comrade-in-arms Captain Taran Penrith, Illeana must unlock the mystery of her own heritage before the past revisits all the people of Indlay in a cataclysm that will leave them changed forever.
