Overall I found this book to be frustrating and disappointing. Based on the reviews I've seen, I'm in the minority - maybe I was grumpy when I read it or maybe I read a completely different book. I've struggled with writing up a review as my thoughts on it are just as jumbled as the book itself. There's just too much going on in the book; but, not a lot of cohesiveness or follow through on what would seem like major events. I got whiplash from spending most of my time snarling "wtf "and shaking my head.
I'm having a hard time classifying it. Mercy, a FBI agent who is left to her own resources to save the child, the profiler and ultimately the world, is smack dab in the middle of a narrative that is chock full of action/adventure, mystery, suspense, romance, humour and immortal entities responsible for order and chaos. Larkin jammed so much into the book and I think if there were less plot points/swerves and more focus on a few, this would have been a more solid read. For the GCLS awards, this was classified as paranormal and maybe that's why I'm having such a problem with it because it probably more of an action book with a loose paranormal driver.
The paranormal aspect comes in through gifts that certain characters possess - Piper, the former FBI Profiler and current damsel in distress, is a photo psychic which means she is able to communicate with the ghost of someone by looking at their picture. As well there is an overarching paranormal aspect that hinges on a rather complex idea (if you start thinking it through) that throughout history there have been two chosen siblings responsible for the good and bad events that happen in the world - you can't have good without bad or bad without good and the author uses the Ying Yang as a way of marking those who are or will be engaged in this ancient cycle. Shadow - the personification of chaos - has gone all in on the idea that evil knows best and is manipulating events like the bombing of the Golden Gate Bridge and releasing a deadly biological agent that will kill off pretty much all of humanity. Why, I'm not sure. I was so stuck on the ridiculous name that I couldn't take him seriously as he wandered through his warehouse of doom, fondling the helmets and boots of dead coal miners and train conductors who died in mass tragedies (tragedies he created). Lucent , his twin, is the embodiment of order/good, but his work seems to be on a smaller scale, saving one orphan at a time, and just doing his best - and he's unaware that his brother has gone batshit crazy. Shadow and Lucent's reign is coming to an end and they are preparing to transfer their responsibilities to the next set of twins - Raze and Mercy. Ugh - parents who name their children Shadow or Raze must know that they are dooming them to an eternity of chaos/evil or at least a childhood of getting the snot kicked out of them in the schoolyard.
The book starts off with a supposed terrorist bombing of the Golden Gate bridge, then its an investigation of a child murder, then a child kidnap, then a cat and mouse game between Mercy and Shadow where he gives instructions and pulls the strings and she dashes around trying to save the child, save the psychic, oops forgot about the kid so go back to save the kid and ultimately save the world. In the meantime, she and Piper meet, exchange banter and fall into bed with no actual relationship or rationale. I think the romance was supposed to demonstrated by the exchange of some seemingly inappropriate humourous banter (inappropriate in the context of what's going on not in the banter itself), ogling of body parts and a convenient stop in a motel room. Things are introduced as major plot points and then fall off the page - someone blows up the Golden Gate Bridge and there's no further discussion/seeming impact, a child is murdered in her home and the next day the parents are adopting a cute orphan that is dropped off on their doorstep, Mercy's colleague is murdered ... they happen and then they disappear off the page. I'm all for suspending my disbelief and just going along for a wild ride or crazy ass action/adventure - but I found it too jarring and disjointed as Mercy runs from one crisis to the next.
There was one thing I did enjoy - the sections of the book that were told from the POV of young Emily (the kidnapped child who teams up with the touched-by-an-angel golden retriever, Bobby). That kid should have been allowed to grow up and be the heroine of the book. She was a bright, kick-ass kid. What she did and why she did it was consistent and actually made sense. Liked the kid, liked the dog.
