"Filled with show me now and tell me later prose, [Miserere] was one of the finest debuts of 2011 and remains a novel that I remember details from nearly three years later." Justin Landon, Tor.com

"Miserere reads like Ladyhawke had a baby in purgatory and Meljean Brook delivered it." -- New York Times Bestselling author Ilona Andrews (read Ilona's review of Miserere).

"Miserere is about redemption, and the triumph of our best impulses over our worst. It's also about swords, monsters, chases, ghosts, magic, court intrigues and battles to the death. It's also (and this is the important part) really, really good." --Alex Bledsoe, author of The Hum and the Shiver, Dark Jenny and The Sword-Edged Blonde (Alex reviews Miserere at his blog ... from down in Lucky Town)

Exiled exorcist Lucian Negru deserted his lover in Hell in exchange for saving his sister Catarina's soul, but Catarina doesn't want salvation. She wants Lucian to help her fulfill her dark covenant with the Fallen Angels by using his power to open the Hell Gates. Catarina intends to lead the Fallen’s hordes out of Hell and into the parallel dimension of Woerld, Heaven’s frontline of defense between Earth and Hell.

When Lucian refuses to help his sister, she imprisons and cripples him, but Lucian learns that Rachael, the lover he betrayed and abandoned in Hell, is dying from a demonic possession. Determined to rescue Rachael from the demon he unleashed on her soul, Lucian flees his sister, but Catarina's wrath isn’t so easy to escape. In the end, she will force him once more to choose between losing Rachael or opening the Hell Gates so the Fallen's hordes may overrun Earth, their last obstacle before reaching Heaven's Gates.
