Most everything in this book testifies to it belonging to Mrs Black's earlier days as a writer. The loose, if not lax, prose mirrors the dark paranormal universe in attendance here in lacking ease and sophistication and polish a good deal, info dumps of very dull and unimaginative stamp being woven into the dialogue in static, awkward fashion:
"'Well maybe I have a right to be angry about my best friend fucking my fiancée while I'm out doing my job to keep this city safe!" Collin threw the glass in his hand towards the wall across the room, shattering it against the plaster, but Marian cried out as if he'd been aiming at her. She was right—he had become angrier lately, but he had good reason. The mages had started a collective—a little group that called themselves the Red Seal, who had been destroying Spiretown one section at a time. That would have been fine with Collin if he'd believed they'd stay contained behind those leaded concrete walls, but they wouldn't, and once they got out, all hell would break loose with them. So far, the tips they'd received had all been dead-ends but he couldn’t stop following them... he knew he was on the verge of something big. Collin combed his fingers through his dark auburn hair, his anger retreating for the moment"
or embedded within the narrative which they considerably slow down, notwithstanding any other considerations, for example when there was the pressing need for further pieces of description (in which case the writing degenerates into extended strings of bland filling materials through the utter thicket of which the thread of the action all this hangs upon gets lost sight of):
"it was five-of-midnight when they rolled into Spiretown. Named for its overabundance of churches, the mage's compound was a blight on the landscape. Broken crosses and crumbling steeples pierced the skyline over abandoned buildings and empty streets. It had been an area plagued by crime and poverty even before the mages had been moved in, and the city was all too happy to hand it over to the Templars for control. The Templars, a name borrowed from the legendary Knights Templar of the Crusades, had been formed during the final stages of the Magewars; a specialized branch that was neither military nor police, and whose sole jurisdiction were magic-users. They had weapons that could disrupt the necessary energy, or mana, that mages drew from the environment, and because Mages could wear no real armor, once their magic was suppressed, they were easily subdued. But it was more than weapons that made a Templar; it was a solemn oath to drain the planet of the evil that mages attracted, by controlling and eventually eliminating all of those who would be magnets. Spiretown was surrounded by a thirty-foot high wall. The only ways in or out of the series of connecting streets and dead-end alleys was the front gate or hidden passages used by the Templars. Ironically, the passages had been obscured by the very magic they sought to contain—another example of an apostate mage selling out his or her own people for personal gain".
Most of the paranormal lore is not even explained out, merely dropped on a need to know basis upon the unfortunate reader, who is left to struggle with more or less hideous lingo and all but self-evident statements of fact:
"he could barely make out the heat-signatures of the bodies from his angle, but the amount and placement of the heat confirmed the arrivals were mages; their hands, torsos, and fabled "third eye" were glowing white-hot".
The breezy, almost desultory tone of the narrative itself is not very conducive to smooth reading, not merely out of itself but also because it clashes with the very dark atmosphere Mrs Black wants the readers to lose themselves into:
"Saint Isolde's stone walls created a decrepit shell around burned-out church pews and squatters' abandoned bedding. Mages seemed to have an affinity for old churches, carrying out their black masses for the obvious irony of it. Collin had broken up more than his share of demonic rituals here and was not entirely surprised to see the faded sigils still etched into the floor. What was surprising, however, was that there were no active wards. Mages were typically a lot more paranoid; they had every reason to be. It was easy getting into the church— and that was a bad sign. They had five mages confirmed inside the main chapel. Collin's guts twisted and he felt that uncomfortable chill that always preceded trouble. He was ready to withdraw and pull his men out when all hell broke loose".
The entire cast of characters does not showcase better writing values and cannot be expected to demonstrate great authorial control, given the painfully contrived web of links established between the leads and their entourage: Collin is your run-off-the-mill paranormal slayer with very little in the way of psychological range who gets saved and then taken control off by rare paranormal Logan, a Dreamer who can kill in his astral projections and who has a vested interest in protecting the half-breed daughter Collin's deputy Philip had with a paranormal, and so on and so forth. The more I can state about the plot itself, that it is merely serviceable, has to do both with the author's poor powers of imagination and the one-dimensional stamp of the universe building and all the characters. Hard to do better with such tepid, formulaic guidelines.
In so many words, an original fanfiction writ large. One star and a half, rounded up because it is not too cringeworthy.
