Read this on my day off. Once I started, I had a hard time putting it down. I loved the continuation of the storyline and world building, though at times there did seem to be a great deal of jumping around from subplot to subplot. The world building was once again very good. The over use of the word "uh" in the dialogue was much less prevalent, so that was a relief. I really enjoyed the dichotomy of Lock and Deep, and Kat was the strongest female protagonist yet in the series. There were a few awkward moments that kept it from reaching 5 star territory for me, but I am looking forward to the advancement of the plot with Xairn in the next book. Now, I know some of you have been rolling your eyes at the "merging" between Lock's and Deep's *ahem* fun parts, but really - it's sci-fi, people. How is that any stranger than sparkling vampires, werewolves, mermaids and all the other weird stuff in romance these days?
