I wasn't sure that I liked the sudden addition of paranormal elements this far into the series. I do like PNR, but I think the KGI series is much better without it. 
 A lot of the dialogue between MCs had me rolling my eyes because it was so corny. Way too much sweet talk going on here. It didn't seem to fit either character. 
 I still love the series and I will definitely be continuing. I just hope the books after Grace gets her HEA will be more like the first few in the series: focusing more on the characters and their skills, with little or no paranormal stuff.
