This was a really enjoyable sequel to the first book where Cyn first met Raphael. The amount of angst Cyn went through when Raphael left her is heart wrenching to read, but it also helps me appreciate the couple better when they eventually got back together. 
 I am very impressed by Cyn's characterisation. Her ability to keep calm in the most dire situations and think of ways to get herself out of the fix is one characteristics that defines her from the Heroine tropes that plague mediocre PNR efforts from other authors. 
 Having hinted at a broader Vampire universe in the first book, Reynolds did a fantastic job expanding it in this book, with the introduction of a second Vampire lord, Jabril. I was really surprised to discover that although this book was titled Jabril, Jabril is not the hero of the book, but rather the villain. The main couple is again Cyn and Raphael, a continuation from the unresolved cliff hanger of the first book. Again this proves a significant departure from other PNR books, where the sequels generally focus on another couples involving other warriors from the 'gang' led by the Hero from the first book. 
 I have always felt sequels in other PNR series a letdown after the first, because the Hero is no longer the 'leader', but rather a less powerful follower. Future books on Rajmund, Duncan and Sophia, who are all vampire lords in their own right, will provide a much needed contrast to the existing PNR catalogue. 
 At this point, I have to note the significant parallels between this series and another favourite series of mine, the Guild Hunter Series by Nalini Singh. While the first 2 books of Vampires in America was dedicated to Raphael and Cyn, the first 3 books of the Guild Hunter series revolved round Raphael and Elena (who later turned from human to Angel). Both the Hero characters are super strong supernatural leaders of their respective territories, supported by an olympics weight-lifting worthy securities team (which have potential for future individual stories), who meets the Heroine by hiring her for some detective work, fell in love on the job and eventually HEA for both of them.
