That was one hell of a ride!
I liken this series to working similar as a season of tv. This is a complete arc and can be read on its own, with a beginning, middle and end. There is room left though for more stories to be told, and if the second series Ms. Hawk is working on is anything like this one, I'll be eager to read it. But I don't know if I can wait months in between books, and she's only halfway through the next series. Dilemma!
I'd sworn off vampire books way back in high school when I tired of Anne Rice, and I really haven't read very many at all since then where the vamps were front and center. There's the Dresden Files, and now this, and both that series and this one do some really refreshing things with their version of vamps. (I guess the Kate Daniels series does too but that whole series was bordering on corn with a hefty side of cheese. ... Cheesy popcorn? Yeah, I think that fits. Starts off promising but you just can't finish the whole bag.) Here, the "vamp" in question only has the blood drinking to liken it to common vamp lore, and even that isn't used in the usual way, so I really enjoyed how everything was changed up and made its own thing. Also, no sparkling. No sparkling is always key to a good vamp story. :D I'm not going to rush and start reading more vamp-centric stories after this, mind you. I really am done with that genre, but I'll make an exception for this series.
I did get rather bored with the sex scenes. Maybe reading these one at a time as they came out, they might not have seemed as numerous. But reading the bundle, one story after another, I just started finding the sex scenes tedious halfway through, and by this one I was skipping them to get back to the plot.
Another thing that got repetitive was how Ms. Hawk reiterated basic information - characters' appearances, basic background info, etc - in each book, I guess so those who decided to come in halfway through wouldn't be lost. It started to drag things out that didn't need to be dragged out. Thankfully, she did keep these bits to the bare minimum, but even those bits I started skimming/skipping. And what is her obsession with tigers? No, stahp!
Once again, Ms. Hawk shows her flare for action as the team figures out the big conspiracy afoot and all the plot threads come together in one epic climax. This is one of those stories I would love to see on the big screen. There's even a new development with J/C/G that opens up all sorts of possibilities for the next series. And then there's Sean, who inspires various complicated feelings. He's easily the most interesting character here and has the most potential to really grow in the next installment.
