Olivia Taylor-Jones discovered in the first book of the Cainsville series that not only was she adopted, but her birth parents are convicted serial killers. She cleared them of one of the murders of which they were accused, but before she can begin investigating any of the others, she sees a dead body dressed to resemble her. Then it vanishes before anybody else can see it.
Although this book was a fun ride, and the murder plot itself was nicely twisty, I felt like the book overall was a bit obvious. My guess from the first book of fairies being behind the weirdness of Cainsville and Olivia and Gabriel having fae blood has been confirmed.
I have some further predictions:
Although Olivia begins a relationship with Ricky in this book: I officially predict that she's going to wind up with Gabriel by the end of the series and that Ricky will more likely than not die in some heroic way. Former fiance James is at this point too obviously either evil or being manipulated by evil supernatural powers to be taken seriously as a potential direction for Olivia to be pulled between the men in her life. On a non-romantic note, Olivia's parents will turn out to be exonerated of all the murders. I'd find it more interesting if they were guilty for various reasons related to their not being human but I feel like the first book set the tone as far as that's concerned.
At this point I'm reading for the ride and to see exactly how the fairies relate to the murders. And a little bit to see if I'm right.
