Cliffhanger. Ugh. Worst part? I know there are, according to her website, two more books: Origin and To Be Named. What that means? Probably an even worse cliffhanger the next time. And considering how Opal ended? I'm almost scared to find out.End result, I will probably not read Origin when it comes out. I will wait until To Be Named is released and read them back to back. Just like I did with Hunger Games. It's easier on my poor heart that way.I'm actually already doing that with her Covenant series. As much as I loved Half-Blood, I'm waiting until the whole thing is released, then I'll pick it back up again. I'm still on the fence about the longer-series arcs over the more traditional trilogy. Sometimes there's enough to make it through 5-6 books. Sometimes those middle books feel more like filler.Which, unfortunately, brings me to Opal. Don't get me wrong, it was a great book. The Katy/Daemon stuff was pretty awesome, I got my desire to kick Blake's nuts into his throat renewed to the point that I actually brought my foot back a few times. We got some new characters introduced, some new carrots dangled, a great finish.But it also dragged a bit for me. I didn't feel the need to sneak off and read it when I shouldn't be reading at all (at work, pretend errands where I really just sit in Starbucks parking lot, hide from my family, and read in peace, etc.) I was alone at work a few times and didn't rush to pull my Kindle out...I played free flow instead. It was fun *while* I was reading it, but it didn't call to me apart from that. The tidbits of plot advancement, the continual 'training with the onyx' mixed with further 'let's be normal' mixed with 'will they or won't they this time' scenes didn't make me dive for the book at every opportunity.Don't get me wrong, I'm still loving the series, but this one probably won't ever be my favorite.
