Mercedes Thompson, mechanic and shapeshifter, lives in a world where the fae were forced to come out to the human population due to the advances in technology: making the secret nature of their species no longer possible. Thus the Gray Lords (the enigmatic leaders of the fae) decided it was time to come out to the humans -- along with the werewolves who revealed their existence recently. Vampires however, remain hidden in shadow fearing what would happen if their existence was discovered.
'Bone Crossed' continues the plotlines expounded in 'Blood Bound' with Stefan, Marsilia, and the vampire seethe. Having murdered Andre and received Stefan's protection in covering it up to keep her safe -- Mercy has nevertheless been waiting for the fallout that would occur when Marsilia (the Mistress of the vampires) finds out about the killing. After all, Stefan can't protect her forever. She's safe until Stefan lands (quite literally) in the middle of her living room a tortured shell of the vampire he once was, and informs her that the Mistress knows. Now she is after a little creative retribution. Some that will not start a war with the werewolves. The other arcs in 'Bone Crossed' is Mercy's continuing relationship with Adam, alpha of the local werewolf pack, and the consequences of the sexual assault from the prior book. There's also the arc tied up in the vampire one of the ghosts in Spokane.
This book was a little patchy. There were a lot of things going on and perhaps, not quite enough space to develop them all sufficiently. The start of the story was incredibly slow and the actual meat of the plot did not get moving until many pages into the book -- what was worse, was that I just wasn't very interested in the Spokane-ghost plotline. There was very little tension and it just wasn't exciting.
The first part of the book was more concerned with character issues and the immediate aftermath of 'Iron Kissed'. I didn't mind. I enjoyed it all, but it did lack the exceptionally graceful pacing of the other novels. I did think there was perhaps a little too much time spent on Adam and Mercy's romantic relationship; I did find that well written, but less is more when it comes to romance. Also, the question of Stefan's feelings for Mercy which are shown strongly throughout 'Bone Crossed' but are left without much development. We still don't know why he's in love with her, and why he holds her higher in his affections than his sheep even. Hopefully Briggs is just leaving this for another book... it does need better clarification. The fact that it was brought up again in the final scene tells me it will be an important point in future novels. At any rate I think that to a man like Stefan, he sees it as a noble thing to love Mercy from afar.
That said, I did enjoy much of this book. There was a lot to like. It was great having Adam and Mercy happy together, Samuel with more of a sense of humour, and it was great having Stefan back. I liked learning more about the vampires and Stefan as a character. His friendship with Mercy is interesting; it's oddly loving and intimate in an old-fashioned reserved way. We didn't see much of Warren, Kyle, Honey, Ben, or even Samuel for that matter (although I hear the next book will focus on Sam, yay!). Mercy's relationship with the little deaf boy Chad was one of best things about the book, and the funny discussions about Superheroes.
Overall, a nice outing, but lacking the quality and tension of the previous volumes.
